This recipe will redirect members to certain pages based on their membership levels.

Tweak this code to your needs by changing the membership id numbers in the pmpro_hasMembershipLevel() checks and changing the URLs in the home_url() calls. In this case, level #1 users are sent to a page at /level-one/, level #2 users are sent to /level-two/, level #3 etc, and all others are sent to the homepage.
