I think that as far as editing posts goes, the original post of the thread should always be editable until it is closed. Especially for trading forums, this would make it much easier for viewers of the thread to read an updated list, without having to read each post about items sold along the way, because the poster can edit each sold item out at any time it is sold.

No, would entice scamming and make scam cases harder to prove. Paul has already stated he has no plans to do this

[x] No

yes ofc 4 me that would be simplier + would cut some ''bump'' because u sold few think or take out/added stuff to ur list
