POWLAX processes player registrations through POWLAX.LeagueApps.com, not this website. The login and membership for this website gives members access to the POWLAX Playbook PDF’s that accompany the POWLAX Master Coach videos.
POWLAX runs lacrosse programs through Parker Recreation and Parker Hawks who handle registrations on their websites. You may be redirected to these sites through the links above.
Having hard time accessing the membership pages
Try using the links under memberships and see if that works. Those pages should allow you to see everything even if you are already a member.
