I've deleted my post by mistake

Speak to an Administrator. All deleted items go to a Trash Can that can be accessed by any Administrator, and can be reinstated quite easily. Try not to do it too often though, eh?

You can't delete threads you started anymore, so if you can't find your thread, look harder, and if you still can't find it, speak to a Mod to see if one of them has had cause to remove it.
