disable Backlog for Usernames/motd / skip motd
Bip should have an function that bip does not backlog Messages and Create log files for user defined usernames.
1 new option in the Config is needed. "dontlog"
So if spamserv,Nickserv,Authserv or userABC sends me one PM, the Message is not backlogged and no Logfile for this User is written.
