Track transaction fees
Our league charges $0.50 per transaction. We charge $0.50 for every add/drop and $0.50 for every player traded. We would like the website to track each owner's transaction fees.
The only leagues where Yahoo! tracks any funds are Pro leagues and Private Cash leagues and in both cases, they only track the payouts of the final results.
You can use the Transaction Log, which can be selected by team, to track the transactions fees and place those fees in the Dues field if you wish. Collecting those fees would be totally up to the commish and the league.
