Sorry, it appears that either the invitation link you used or the pool id# and pool entry code information that you have are no longer valid. Please contact your pool manager (or the person who invited you to the pool) to confirm the correct pool ID# and pool entry code.
This season worked out great. I had been managing a 5-0 pool manually up until this season and what a difference having a site to do it all makes. Thanks for having the site work so perfectly.
