It seems that you've added a "feature" to submitting posts?

I found, if I submit a post, but forgot to add an attachment, if I quote it, edit the tags out, and attach whatever attachment I meant to have,
after submitting, then the accidental post has been removed.

It seems that if you submit 2 posts, where the text is identical, 1 after the other, then the first one is deleted.

Thanks!
