How many post before I can sell?

20 posts
(Not spamming to make 20)
Plus a time delay

Or upgrade to platinum for instant access

The timeframe hasn't been published by the moderators
It's a minimum time so you don't get reset for taking too long

As a long time member with under 20 posts you're one of those who have had access before but don't meet the rule criteria

The time delay was put in on top of the 20 posts recently

 

Yes 20 minimum, unless you score some bonus brownie points and a kindly moderator fast forwards you !
