Ok here's the deal. I need for my users to connect to three different chat servers and about two dozen channels. This need to be automatic when mIRC is launced.
What do you mean your 'users'? You can't control what other people's mIRC clients do, and cannot make people connect to multiple servers, even if you own one network that they connect to.
Actually, in this case mIRC is being used in a private network and I do control where the members of my domain, who use my network, AKA "Users" connect to.
