It is WRONG to allow commisioners to renew their prior leagues teams. STOP THIS!!!
Do NOT allow commissioners to automatically renew their prior league's teams. I was shocked to have this happen to me. Fortunately he hadn't finalized it and I was able to delete it. This is WRONG and should not be allowed. I can't believe you give the commish the power to do this.

I'm a commish, and don't really get the problem on this one. I renewed the league for the year, always the same teams, and it automatically included all of the teams. In the past, they all had to accept the invite that went out and it was a pain to wait for them all to join, when in the end they all mostly did. When one wanted out, it gave me a chance to have another player take over their team, something good being a keeper league. For a player to delete their team doesn't seem too hard; but maybe I'm missing something about your concern.
