While we're bringing the first few charters on board, we will be disabling the "player-initiated" side of the claiming a player profile (and thus become a member) process (we have also temporarily disabled the "Create Confirmed & Rogue Profile" sections at the bottom of this page).
For now, to claim your player profile (so you can create scoresheets and enter and submit match data through this site), contact a Charter Admin (CA) of a charter you're playing in a league or tournament under, tell them you'd like to claim your player profile on the ppmu site and give them your name and email address.
The CA will then send you an invitation email. Click on the "Invitation Link" in the email. This will link you back to the ppmu site. Click the "Claim Profile" button and you've claimed your profile.
