How to handle misplaced posts?

[viv]

It would be good to have an opportunity to delete your own thread or at least let moderator know if you accidently put it into wrong forum or found that is is a repost or a dead deal right away. Otherwise such posts clutter the forums and cause a negative reactions (thumb down) from other SDers. Thanks.

if the thread has more than 1 post, mod alert any post with a note saying you want to move it.

if not, a pm to the mods can also accomplish it.
