I believe I am not 100% sure, cause I haven't done it in a bit, but if you go to edit your post, like once your post is already posted. Within that same function within edit, at the top I believe it should ask you whether you want to delete the post.Click yes and then click delete now. Then from there it should be done
Hope this helps
hmm I am not sure what might have happened then, I just wrote a message and then just deleted. So maybe the system was semi down or something. If you really want your message deleted though and it's still not working, I think if you PM the mod for whichever forum, they should be able to delete it for you
hope that helps
