Most forums get around this issue by activating a feature whereby the user can edit their own posts only within a certain timespan (e.g. 1 day, 7 days etc.).
After that the post is locked and only a moderator can edit it.
I think this makes sense. Generally there should be little reason why a post which is older than x amount of time should be re-edited by its OP.
