Hey I have the same problem but what if I need to register my nickname to one of those servers or to multiple servers by "msg nickserv password" before I join channels. what would I add to this line of the config...

n6=server -m irc.Global-Dimension.org 6667 -i, cX_GX cX_GX_,-j #channel

I still have a couple other servers to connect to and different nickserv passys for each.
