The title is required, and must contain letters and/or digits.
It's good to see El Reg post these guidelines, but may I make a few suggestions:
1) The author of an article should have no ability to moderate (or edit) comments. If allowed, this simply leads to a blatant conflict of interest. Also the decision to allow/ not allow comments on an article should be down to El Reg's Editorial or Moderation team, not the individual author.
2) If an article is based on the author's opinion of a published work etc, it should be clearly marked as such. Occasionally some articles have appeared in El Reg which are extraordinarily one-sided yet not marked as "Comment" or "Opinion".
3) It would be useful if, in the "My Posts" section, there was an indication of whether someone else had replied to your comment (eg a line saying "2 replies") to save having to check each one to see if someone has responded.
4) Since you can tick a box to post anonymously, why not have a box to tick that comes up with [NO TITLE], or if you reply to someone else's post without including a title of your own, have the forum system stick in Re: [previous title]
