Simple suggestion here: Please turn on the ability to edit posts. There's really no reason this feature should be disabled.
There is a function to do this. I use it all the time! (I use the swipe keyboard input on my phone, and I've posted some really random stuff, so thank goodness!) There's a small more button at the bottom right of your post.
There's no More button at the bottom right of any of my posts. As shown: EDIT: Okay, this is really odd. This comment has an edit button in the bottom left. None of my other posts and comments do. Any admin care to let us know what's up? Bug? Intended?
New members have it for a duration of time after they make a post (for quick edits). Elite Pilots have a MUCH longer ability to edit their posts.
