I am wondering if in a league in which the majority of people own the program and send in files if there is a good way to be able to have more than 1 person act as commissioner and sim the games without it causing any type of error in the program at all. Is it as simple as send the commissioner file as you would a team file and allow that person to sim and then send the files all back or is there something more complex that would need to be done?

Thanks!

The commissioner file isn't a separate file. It's all contained in the master league file. All you'd need to do to have more than one commish is to give whoever is acting as the simmer the commissioner password login.

Most leagues have 2, maybe 3 simmers. But it should be the GM(s) you place complete trust in their integrity.
