Trial account and recurring billing
It would be nice to let users try our classifieds board before submitting an ad.
Example:
You can post 1 ad for 30 days for free. If you like it, you'll pay the next time. If you try to post again, you'll be asked to pay...
Recurring billing
I think somebody already asked for it... if a user pay every month for his/her AD to be listed, the ad will not expire until there's a valid subscription running.
Thanks
