@indigomoth - I'll second that you should look for forums with one caveat.
I think when you are starting out with a new craft type, and learning a bunch of basic techniques, it can be easy to spread yourself too thin. This doesn't matter so much if you are learning for fun, but if you're hoping to develop your skills and maybe eventually sell some jewelry, you need to focus a little more.
Don't try every little thing on the forums. There are too many techniques to focus on all at once. Find a few that look interesting and practice them until you have them right.
This way, you can develop your own style without just scraping the surface of a bunch of other peoples' styles.
Copper jewelry making is a lot of fun though and can produce some gorgeous items. Good luck!
