Sarcasm or no, you should, mystery people are intriguing and should be pointed out and scrutinized whenever possible. (I have too much time on my hands)

Do it.


But seriously, just think about it, Acute Angle really is a mystery. Is she 'the law' or is some other organization gathering info? There is always the slim possibility that she just likes to read the various threads and doesn't like to post, but then why register and why use an avatar?

The only reason i can think of for her to register is so that she can receive email notification of replies to posts and threads of her choosing. Perhaps gathering info on all our little tricks of the trade. (I've never used this function, but I assume it works)
