Yesterday I posted in error and decided to use the "delete" button and remove my mistake. However after being asked for a reason (which I supplied) the end result was that the forum software told me it could not delete the post, I believe because I didn't have sufficient privileges. Tom, could you please this through your sock puppet test account? Alternately, if you don't want to let members delete posts then you should disappear the delete option. Even if you prefer to set the software so that members cannot delete posts they'll just edit their erroneous post to say something like "posted in error," so there's no practical way to force members to not effectively delete posts. Might as well just fix it so they can.
