Hi everyone! Ross, I just came across your Feb 2010 post, "10 must-read Facebook resources for non-profits," and I noticed one of the resources is "Top ten Facebook charity applications." I hope it's alright for us to get a digg in here while we're on the subject :P...
We created a Facebook application CMS module for our clients that comes standard with all Effect Engine CMS-powered websites. It's called SIDMA (Social Information Dissemination Management Application) for now, but we are thinking about instead calling it 'Facebook Wildfire' since that is pretty much what the application is in a nutshell. It's pretty powerful stuff!
I hope you all will check it out in brief at

All the best!
