If you are careful about what you're doing, then you should be ok. As long as you DO NOT post a thread to ask a question--that leads to instant locking and a huge stigma to carry around. If you've been lurking for some time, then you probably know this. I'd suggest hanging around areas like specific pokemon discussion threads, the suspects stats thread, or the general discussion thread. If you're really bold and you've been lurking for some time, then you could head over to the suspect thread, but the people there are often a bit more serious than the rest of the OU forum. As long as you can make a good impression, then you should be ok. Welcome to smogon, I suppose!
