I ran a pool with you last season. Do I need to start a new pool this season?

No. In fact, we strongly suggest that you use your existing pool. Your pool settings and members are maintained from one season to the next and you have several member maintenance options available to you. Using a previous season's pool also helps prevent pool member confusion about which account to use, where they entered picks, etc.

All pool settings (including the pool name, in case it has the year in it) can be changed by going to Commissioner Console --> Edit Pool Settings.
