Forum Software Info
Forum56 runs on the open-source ASP Forum software available from Asp-Dev.com.
I've personally modified quite a bit of the code: while the basic "beta" code that's listed on the site as "new" works and has only a few bugs, I wasn't totally satisfied. So, I've modified almost every module in the package myself.
Other third parties have developed enhancements based upon the original open-source code, and some offer these enhanced versions for a fee.
While the Forum may look like the very popular UBS boards, the technology behind it is very different. With ASP, all the information in the Forum is in an on-line database (MS Access or SQL). UBS uses scripts and creates a separate HTML file for each topic. On a popular board, this means tens of thousands of files on the server!
Modifications I've made include e-mail reply notifications, send topic to a friend, post and edit enhancements, the 'nomail' option, private mail option, a search function that works, and many more.
