How to delete a published post here?
I don't think anyone other than the mods can move or delete a post. You can use the edit function to remove the content from a post of yours. You should leave a message behind like "Post redacted by poster" so people know what happened. If you want to delete a thread you started in an incorrect subforum, you should contact a mod concerning that.
Post redacted by poster, is a good idea. Added to my notes.
