Oh, Mel, dear, ignore young Hookbill, here. He'll suck you right into Mount Zoom if you aren't careful.
Suggestions depend on what you're interested in. If you like to write, check out the RP forums. The Green Dragon is in the Shire and the Eorling Mead Hall is in Rohan; both are good places to go, but I'm admittedly prejudiced in favor of the Hall. If you're feeling ambitious and argumentative, head to Books. It'll teach you to argue at the level of college research papers if you get the right people up against you. You'll find a lot of laughter in Mirth, basic questions answered in Novices and Newcomers.
Like I said, it's all up to what you feel like doing.
Welcome also to Raewyn. No worries on your English, love, you've got a better grasp of it than most of my native-speaker friends.
