For most of our pools, entry names can be changed on your entries page within the pool. Click on the appropriate pool membership on your Pool Memberships page. Once in the pool, navigate to the 'Your Picks' tab and click the 'rename' link next to the entry you would like to change.
For our Squares pools, entry names for our squares format can be changed on the 'My Pool Memberships' page using the 'Options' drop down on the right hand side.
