Ok. that solves problem #1.Thanks!

Problem with nickserv is that many channels need +r to let you in. Thus, mirc built in rejoin functions doesn't work. Puttin it into preform (as well with timer to join channel) for each channel for each network is really tiresome:/

Regarding nicks, I'll investigate the script suggestions.

Another question - how can I make irc connect to certain networks on startup?
