I posted an answer to a question and it's been deleted. Why!?
As we head in to Ubuntu 11.10 release I'd like to make sure when we are going through the site and marking items for removal in this (and any) clean up period we're leaving notices to users as to what is really going on.
This is designed to be a Community Wiki FAQ where each answer is a brief reason why a post may be deleted and how to remedy this. Please at least leave a comment with at least a link to the reason why the post is (or is flagged to be) delete.
