Definately it can be done. MSDN Forums are running on .Net. While they aren't exactly like the UT, there are similarities. If you're interested doing something similar with .Net, the quickest way to get started would be with something like .Net Nuke (www.dotnetnuke.com)

>Thanks Plinio and Hilmar... Now... Is it possible to create a site like UT only with .NET tech? I mean, it seems VFP is te easiest way to achieve it.
