Two ColdFusion User Group sites--the Bay Area CFUG run by Sean Corfield, and the Boston CFUG run by Brian Rinaldi--recently launched using the user group management application I created for the Capitol Hill User Group. Sean also very graciously contributed some fixes to the code before he went live with it.
Just pointing this out again if you're in need of a user group management app. Also if you want to dive in and help with the code on the project, just let me know.
Just a quick note to let you know that we're using CHUG over here for the Scottish ColdFusion User Group site.
