Sometimes you make a typo, or you think "I could have said this clearer/nicer" - then it would be nice if you could edit your own posts.
Deleting your own posts (e.g. in case of duplicates, see https://100stamps.club/discussions/messages/352) would be nice too.
This could be limited to 10 minutes after the initial post, if you want to prevent people from removing the answer history.
