Ive used a lot of forums and most of the other forums i used, we were able to edit the our posts.
Of course we are able to edit out posts but after like 5 mins we are unable to edit it. For those
people who make huge trade lists, once they sell something they usually make a new post telling
the others that the item is sold. I also think we should be allowed to edit the first post so users dont
have to look through all the pages when all the main info is on the first page.

Its 30 minutes, and a longer period would be abused
