Guild's start at 50 player cap for 1 silver upon creation. It can then be raised to a maximum of 500 cap for increasing amounts of silver (I think it was less than 10 to get it to 100 cap like we had in the beta - ask shinboy). The main thing is that you have to be a certain size in order to unlock the next tier of cap - though we got it working in the beta, so it shouldn't be impossible come release.
