Does afterdawn use cold fusion for this site? I would love to have a forum like this for network security.
Yes, we use ColdFusion. The forum software is 100% developed in-house by me and is capable of handling appx. 15-20M page impressions a month on a setup where you have one dedicated web server running Apache + CFMX and one dedicated database server running mySQL (or any db of your choice). I have had plans for years to turn the forum software into "out-of-box" forum software and license it for others to use or turn it into open source project, but I never have enough time to do so
