If you notice someone who's posts you keep finding to be gems of wisdom, or someone who clearly has what you want, you may approach them respectfully via PM. tell them how you feel and ask if you might pick their brain on a subject.
They may be willing or not. If not, move on.
get to know a few people in the chat room the same way, or even by posting and reading...
In time you will find a few that you really mesh with, and some fellowship will grow organically, but don't be afraid to say "hey, I think you have something I need, do you have some time?"
welcome,
today can be the day you live up to your screen name
