If you want to be a part of this League next year, you need to be active on here when the Leagues are done. Two or three times people have lost their spot in PL because they returned to the site, and expressed their interest, too late!!!!
There will be between 2 and probably 4 changes next season, as there are every season. Also keep in mind, your activity on the site is more important than your place on the ladder, though both things come into calculations.
