You should also be able to go into any branch of the deposit account's bank and make a deposit to that account, by cash, without incurring any fees. This isn't a "wire" or "TT" which is the type of transfer that would incur the $20+ fee Bitt mentioned.

I say just keep it simple and have people send a check made payable to whomever is collecting the money. The biggest danger here is that some cheque may be made out to the incorrect name, making them impossible/difficult to cash/deposit.
