I agree with Warwynd, research is important! A huge help can be to talk to the org owner / matchmaker before signing, to explain your situation (being new) and what plans they might have for you... just talking to them shows that you aren't a fly-by-night never sign back in after signing a contract type... They'll appreciate the enthusiasm and most people love the fact that they might help a new manager become a complete addict.
Keep going, even if you get a bad contract or two, and when accepting or declining a fight or contract, there is a message box to add to the reply, and everyone appreciates those, to know better about how THEY are doing!
