For the matches are there proper leagues, or do you just pick who you want to play against by challenging them to a match? I don't think it'd be worth the monthly fee if there wasn't a decent league system.
- Friendlies - approach anyone online and ask them for a friendly - Senior and Under 21's both allowed. Ranked and Un-Ranked too
- User created competitions - Leagues/Cups etc. pay an entry fee and the host decides the prize money, rules etc. Some good, some bad.
Future (as far as i am aware)
- Federations - when Federations are formed official leagues will be formed. As will user made competitions within the Federation
- Fed. pt.2 - read something about 'World Cups' where top Federation teams play other top Fed. teams
