I wonder why you didn't ask this when you were a newbie and new to the forum, and i also wonder how you didn't find any signature thread, while there are many posted each day, after spending so much time on the forum and getting 42 activity points which clearly means you have spent more than 42 days on the forum. Well, if you bought this account, and that is why you don't know anything yet, then you got it now. Like everyone said, head to Services section and you will find them there. There is also a thread where all the campaigns are listed. Below is the link to that.
