He's almost certainly talking about , which are commonly abbreviated to "DT". I'd be like reading a post which stated "I am an immortal on the MUD Primal Khaos, a Greek mythology themed Hack'n'Slash mud ... we have gotten a few new players who have expressed that they love PK" and assuming that "PK" stood for Player Killing (which would be unfortunate if you hate Player Killing).

Regarding the original question, it's pretty widely accepted that the vast majority of newbies quit within the first few minutes. It happens everywhere. While that certainly doesn't mean you shouldn't try to improve the newbie experience, it also doesn't necessarily mean you're doing anything wrong.
