Hi,
I didn't have the same experience as you. What I had was unability to change a post's category (as I didn't know the first tag was the category that will never be changed), my post ended up in an unsuitable category, so I rewrote it in a new category and got a warning from cheetah :). I intended to delete the first post but that was not possible as people had already up voted it, neither could I edit it (to empty it). I learned that I should have considered my tags more carefully and read the white paper :). Glad you could make it back ;).
