I have some exciting news to offer... For those who have short attention spans, just check out http://bahai9.com which is now back online to editing.
For those who can spare a little more time, please continue reading... If you consider yourself a regular at this discussion board, I would strongly urge you to see the site above and read the following....
------------------------------------------------------------------
The site has been around for a while, but we weren't able to open it again to editing until now. The site refers back to articles and the Writings hosted at http://bahai-library.com . While http://reference.bahai.org is the official source of the Writings (and we have used their works on site here), having copies on site here has the advantage of allowing us to integrate back to the wiki as well.
You may notice that while visiting pages such as those on the Writings at this http://bahai-library.com site that the top right-hand corner offers a link to allow you to add information for the given book--this is just the beginning of the integration I'm hoping we can have of the power of unity-in-diversity collaboration with the transformative power of the Holy Writings.
We were also able to upgrade in a way that the site now supports "Unicode" (UTF-8), meaning that we can include content in any number of different written scripts of the world (e.g., Arabic, etc.), all within the same page even (though we'll need to have some established/trusted reviewers if we end up having articles in languages other than English).
The main page is locked since it is prominent, so you can't edit that page (though you can suggest edits to it in a page linked from that page), but almost all other pages at the site can be edited by registered users (we are requiring registration to avoid spam mostly). Of course, the site is from a "Baha'i Point of View". Having our own site also allows us to create shortcut links like "ka:" to make a link to the Kitab-i-Aqdas. There's a reason why the word "wiki" (which means "fast" in Hawaiian) was applied to these sites! It's very easy to create links and add new pages! Wikipedia has become the world's largest encyclopedia and started only in 2001--will our site be comparable for the Baha'i community? Your participation will tell...

Other web resources such as the Baha'i-run http://bahaikipedia.org/ or the publicly-run http://wikipedia.org (which has some Baha'i articles) may be complementary to this site. There is no doubt a place for introductory articles such as these sites have, but again, http://bahai9.com is not meant as such a venue, but rather as a compendium of what the Writings have to say on a particular topic as well as links to secondary resources.
As the site explains, the policy at the site will almost exclusively be to rely on the Writings to speak for themselves, in the spirit of Lights-of-Guidance or the Baha'i World Centre Research Department's bulleted and cross-referenced synopses (see the Summary at http://bahai9.com/Writings_Buddhist_authenticity for an example of this--most of the others thus far are closer to the former), thus allowing someone who wants to know what the Writings have to say on a particular topic, to be able to find it for themselves. However, we can provide links to relevant resources such as study guides, if they do not overwhelm the site's focus (or of course lead to biased sites antagonistic to the Faith or institutions; genuinely neutral articles such as a link back to a relevant Wikipedia page is welcome, however, and should be educational--e.g., after reading the Writings on medicine, one can conveniently browse Wikipedia for a scientific/historic perspective on the articles--and perhaps in some cases even lead back to our site).
I really hope that the regulars here will make particular use of and contribute to the wiki so that we can build, in an organized and collaborative fashion, a powerful resource which can be referenced here in the future when the same topics come up here again (as they often do)--and be useful in and of itself)--especially as more people become interested in the Faith, as we need to be able to address their questions efficiently as well as doing so as well as possible.
Looking from the other side, the discussion pages at the wiki (while normally for merely discussing how to shape the article) can be used for asking questions, just as with this forum (but your question will be in a centralized place, rather than buried in some thread which may never be visited again--it also shows that you (I'm mostly speaking for Baha'is here) took a little time to research the answer first and might have found a gap in the wiki that needs to be filled).
Again, I really do hope you will take a look and consider contributing to the pages. If you have time to make a mini-compilation to answer someone's question here, why not amplify your work for future reuse by integrating your compilation into the wiki (but quotations with summarized headings--quotations alone are too large to be helpful for quick navigation and information-finding) or get in the habit of preparing your answer for the wiki and then respond to people here?
Please do take a look also at the quotations at http://bahai9.com/wiki/Bah%C3%A1%27%C3%AD_wiki_quotes for quotations speaking to the power of our working together, as opposed to independently, as sometimes even dedicated Baha'is end up doing. I recall reading of a dream of 'Abdu'l-Baha where He was to have said to the effect that although in His dream the believers were playing beautiful music, it sounded cacophonous because of the fact that they were not playing in harmony with the other believers. I hope we can all work and play in harmony--it will be interesting to see how people can better organize the Writings and better draw our attention to its gems of Truth, and build positively on the work of others, as wikis are so capable of enabling...
Happy Ridvan!!!
