Pronounced Minus. Sorry, we've been having to use "mindotus" as username on twitter,facebook etc.. as minus is taken. Still trying to get twitter to release Minus w/o any luck :\

If you get a US tradmark number Twitter should release it in short order.

Thanks, we're just waiting for it to happen :)

Can you trademark an existing word?

You can trademark anything you want. It just might not hold up if it gets challenged.
