We have scheduled our purge of inactive affiliates for this Friday, February 5th. This is to allow for such things as orders coming in by postal mail to reach us. Hence, we will be actually looking back a total of 65 days for the minimum 500 points requirement. i.e. If you have 500 points anytime in the 65 days between December 2, 2009 and February 5th, 2010, you're all set.

Note that this also means that we'll be counting any points generated up until the purge is started this Friday. So you still have time to get points yourself and get inactive affiliates in your group active as well.
