If you are looking for a signature campaign, check this[1] overview thread. Keep in mind though, that some[2] might look down on you just because you are "whoring out" your signature. It is also important to understand that you might be banned faster for spam if you are wearing a paid signature. The usual advise would be to just post like you would without the signature, but for some this does not cut it. Keep your posts helpfull and informative. You have nothing to contribute to a discussion, dont post it. In any case, enjoy your stay, leaning all the do's and don't might take time, but IMHO its worth it.
