I updated Regular Expression Library last night and sent out emails to about 700 people letting them know. I apologize that at the moment I neglected to include a way to edit your profile or reset your password, so for now users are stuck with ugly random strings as passwords, but I should have that corrected in the next day or two, at which point I'll send out another email (the last I promise).
The new site is running on its own separate database (it had been using the same one as ASPAlliance.com), has implemented some more efficient data access and cache techniques, and is now using ASP.NET 2.0 (which for now means little to users but will mean easier updates in the future). Please let me know if you find anything wrong with the site (via the site's Contact page).
