I played in APA previously. Do I return at the same skill level or do I start over as a new player?

After your first match, your skill level is calculated. It is against the rules
for a player to attempt to reestablish their skill level. You cannot rejoin
the League or transfer to another League area and start playing as a
non-rated player. You are obligated to disclose the fact that you are a
former member or a current member in another League area and that
you have an existing skill level.
