You can report yourself to a moderator.
You can also consider if anyone else could benifit from your mistake.
If you posted a problem, then find the solution, post the solution as reply to your original post.
(Replying will also remove it from the zero-reply threads - limiting exposure. You can also edit it so the word "fixed" or "solved" appears in the title and/or the first line.)
Remember, no matter how dumb the mistake, there's always someone else doing it to keep you company - besides, a decent mistake can actually be better than a good question.
What to do depends on the mistake. eg. Sometimes it's a accidental double-post. In which case it is acceptable to erase the lot and post "oops - double post" in it's place.
In general, try to put the community good forward.
This will build your reputation better than any correct answer.
