as the title states, it can be frustrating to have no option to sell CAs unless going to the forums, and waiting week(s) for someone to maybe be interested and post.
can we have a section that allows for CA resales?
it could even come with an extra bit of coding which - when you select the CA - detects what its original sale price from the creator is - and it won't allow the reseller to ask for more than what its original value was (for example if they bought it for 40ms, the system would cap it at 40ms, but they could sell it at a discount or the same price bought for).
