As many of our users know, for a brief period we encountered a high rate of non payers amongst "free" email addresses, and at the time we took the step to ban the registration of people from those email addresses.
Lately we have had quite a few registrants who would've like to join but don't have a regular email address, concurrently we have also been very effective at selling our listings and our users are following through on all sales.
Therefore we have decided to relax the free email address policy and provided we do not not see an increase in non-payment, they will stay that way for the foreseeable future.
