During the past months and especially during "Legends on Tour" event we received requests to get unlimited editing function on forum back as a test. This feature already enabled in current settings. Please, keep in mind, that if it works badly in any of the community due to the players violating that option, we'll have to get back to the possibility to edit posts only within certain interval (20 min).
Also, if we ever run events on forum with the rewards to the player, who first posted some answer, we'll set restriction back for a short period of time to keep the fair play.
I hope you'll like that change and we can keep that setting (unlimited post editing) forever.
