A couple people have registered in order to send me a PM (for help with hex editing or one of the bug fix procedures), rather than posting a message.
Some people may have registered intending to post a question, but then figured it out themselves, or tried one last search before posting and got what they needed.
Some web forums require you to register in order to use the search function (which is stupid, so I never do). People used to that may just automatically register before even trying to search.
