[Alumiyum]

First, seek advice from the previous treasurer and your advisers. Then find a way to gently remind your brothers that if they aren't financially supporting the chapter they are not being good brothers. That is part of the package and part of the commitment. If some are having genuine money problems they need to come talk to you in private and try to work out a way to pay. Otherwise, they must pay end of story.

And I'll say this...I know that fraternities are very different from sororities, but one solution is to remove privileges when people do not pay. And that is fair. Except for those that might have a real reason for not being able to pay, there's no excuse, and if they don't support the chapter financially there's something to be said for losing privileges. That may or may not work for your chapter but it's something to consider.
