Well, it does seem he is the same person in all 3 posts. 1: when the Mike and Charlie posts were posted, they were jsut a few mins apart, and then his jimbob account posted jsut minutes later.
Also, the Charlie and Mike accounts were both created today (same day of starting this thread)
I am not trying to get you in trouble, but this is just a little hint to admins if they wanted to.
If you really want to find out if they are the same person, look at the IP address of the members/posts. (im sure you already knew how to do this, just as i do because i have a forum of my own)
