As I mentioned earlier, there is a small handful of GRASS users hanging
out on the IRC channel GRASS GIS on irc.freenode.net. Today we had the
pleasure of seeing Markus Neteler drop in - so don't be afraid 
More
developers are needed to help answer the occassional new user question.
If you'd like more information about how to use IRC, let me know, or do
a web search. One easy to use cross-platform client tool is ChatZilla -
an add-on to Firefox.
