Okay, I have configured mIRC to open up 3 channels when it starts up.
I have mainly used "Perform on Connect" located in main options/connect/options.
This is how I did it using "Perform on Connect" in main options/connect/options:
channel 1:
/server -m irc.<server>.net -j <#channel>
channel 2:
/server -m irc.<server>.net -j <#channel>
channel 3:
/server -m irc.<server>.net -j <#channel>
I have various other commands on each channel listed below the aformention peform commands like /msg <bot> xdcc send #x and /notify <bot>
Could I do all this from the first network's "Peform on Connect" by linking a string of -m, -j & /msg commands?
