Just wanted to raise a UI issue in forum posting since its kinda annoying. If I dutifully add tags I am told that there is a maximum of 6 tags to be added. Whats not clear is that if you select a forum category and sub category, these also count as tags, so if you've been good and put in a category and sub category, you actually only get 4 tags. It would be useful to update the error shown to that effect.

Error Message": "There can be only be a maximum of six tags on a single item."
