I am a founder/co-founder of a couple of Web database projects and have created pages relating to Katrina and the Muslim and Pakistani communities respectively. (Of course, there's a lot of overlap.)
If you know of things happening around the world, where you are, etc. please send me web links and other material that should be included on those pages. In the latter case, you can just click on the "Edit" link at the top of the page and enter/edit information directly.
By way of information, WikiPakistan is a relatively new Information Database about Pakistan, Pakistanis and the diaspora. The site is at http://pakistan.wikicities.com
The Human Rights Project at ProgressiveIslam.Org is is a "wiki" devoted to documenting human rights issues within the Muslim community world-wide. More information is at http://humanrights.progressive
