I know you might think IRC is a bit “out”… But… On server irc.freenode.net you can find fantastic channels like:

#Windows – Windows related questions and discussions
#Windows-Server – Windows server realated stuff…
#Powershell – Powershell stuff…

If you want realy quick answers or maybe some advices to folow… Get an IRC client for example mIRC, get connected to server irc.freenode.org and join those channels…
