no the links work fine without the port number, i think u are misunderstanding my question....
that kind of link works fine, by clicking one, mIRC will open, connect to the network, then join the channel. however since i have more than one mIRC client installed, i want to be able to change which one loads by default. I think it has to do something with a registry file but I'm not sure...any other help? this is a tough one...
