His server was modding content? Woah, didn't know that.
His was the one that had the client's name in it, right?
It just used a server command issued to a client that parses in a line as if it came from the console, so you can mess with configuration and such. There wasn't really any media modification, so I guess she's 50% right. (I think the command is still there, it just prints it out to the console now too -- I don't see why it's even there anymore anyway, as it has very limited use).
As a side note, I never even looked at or modified DP's source once; I think it could be a very annoying general quake 2 problem also.
The server with a client's name it in was just for general fun/annoyance; I used a second (private) one for jacking with people. lawd I loves me that e-drama...
