The creator of a Custom League must supply the league ID# and password to members in order for them to join.

If you created a Private League and can't remember the league ID#:

1. Go to the Yahoo! Fantasy Baseball home page.
2. Click on the league name in the right-hand column.
3. The league name and ID# are shown near the top of the page.

The commissioner can also simply reinvite managers into their league from the Commissioner Tools.

If you have been invited to join a Custom League and can't remember the league ID#, you will need to contact the league commissioner to receive the information required to join the league.
