You have access to all of the add-on items in Yahoo! Sports Fantasy Football PLUS from the time you sign up until the end of professional football's 2007 regular season.
There's no access to any of the functionality during the post-season, and purchases do not carry over to the following regular season.
For the 2007 Yahoo! Sports Fantasy Football PLUS season, payment of an entry fee of $24.99 is required to register a team. You can purchase a league that up to 20 managers may join for $124.99.
Please note that teams can only be played under the Yahoo! ID with which they were created, and cannot be transferred to another Yahoo! ID or played by another person.
If you purchase a league, any user with the appropriate League ID and Password can operate a team. Prospective league members just need to enter the required information after choosing the "Join Prepaid League" option on the Fantasy Football PLUS home page.
If you want to create a league with your friends, you have to purchase a league or have each member sign up for their own team separately using the appropriate Yahoo! ID.
