regularly?
- v7n
from time to time (that is, when I do have some spare time)
- developerfusion.com
- forums.asp.net
I don't find time to visit the others (and I have accounts on every major forum on the web, or, at least I had...)
edit:
btw, Welcome to v7n!
I read your intro and I like it!
I hope you have a very pleasant stay here!
