Dear Admin,

I would like to ask how to register new name of network to new version of mirc

If you're really talking about a new IRC network, rather than something else, an email to Khaled describing it is your best bet. Please keep in mind that networks come and go with regularity, and I doubt Khaled wants to spend a lot of time coding the network/servers list for something highly temporary.

Just found this on another post, which should answer all your questions: http://www.mirc.com/serverlist.html
