This posting is spawned from: Renewals with Free Ads Number Set
Just to move this topic to this forum so that it may be considered in future upgrades.
There are some conflicts arising when using limited numbers of free ads with paid ads.
Could you add another field or to store the ad info, free or paid, then check it at renewal time or something along those lines.
I suppose that when a users free ads move to sold or are deleted, then the renewal on a paid ad should move to free when its time comes.
This could be a good step towards a user having and keep his free ad regardless of if they purchased more ads.
