You can see in the description of the majority of the boards here the Mr. Do is a mod. I can't understand how you could have missed that if you have read the boards before and I doubt you just stumbled onto them today. If you didn't know, it's not ok to take someone's user name and change something tiny and use it, like if someone signed up with "Smitdog" that would not last long. I also got a message from someone saying you are a known troll, a particularly annoying one, and signing up on other places with known regulars' names with tiny things changed, but I don't have any proof so I'm giving you the benefit of the doubt for now. Either way, you can't use that user name, so you need to change it.
