I can't comment on the platform other websites use, and whether that techniically what is being asked for is even possible on FT, but I will say there is an element of swings-and-roundabouts here.

Most sites:
- allow deletion for a period of time
- restrict editing of posts after a period
- auto-close threads for non-activity, meaning no further changes can be made

Often, allowing unfettered deletion can completely destroy the sense of the thread because responses to pertinent information become meaningless without context. Members apply time and thought to those responses, so it's disrespectful just to effectively throw them aside.

Flyertalk does not allow deletion, but members do have the ability to edit forever (provided the thread remains open, and I'd estimate in excess of 99% of ours are due to our non-closure policy). That gives everyone the opportunity to go back and correct anything as they wish, forever. Complete deletion is possible at mod level - we have a report triangle, just use it. Moderators are never unsympathetic to genuine requests or errors.

I'm going to close this thread here. If you'd like a technical explanation on whether or not it's even possible to easily introduce a member-level deletion, please feel free to ask the question in the Tech Support forum.
