Forums mIRC Help Pause, how?

mIRC uses timers. See /help /timer
E.g. /.timer 1 5 msg ChannelBot etc.

That said, instead of just sending the commands like that, I would recommend identifying to NickServ upon receiving the NOTICE from NickServ asking you to identify (see /help on notice) and sending your msg to the bot after NickServ sends you the notice that you have successfully identified.
