After you request a free shell you need to come to our IRC network channel #shells and wait until your shell will be activated (it can take up to 24hours). And remeber if you not come to our IRC , your account will be disabled after one week because of use irc activity based system. I prefer you to use some nick/account name on both shell/irc.
The main load balanced server is irc.bsdnet.net
You can simply connect to BSDNet using /server irc.bsdnet.net command on your irc client. Then you can join #shells channel by typing /join #shells
ALSO NOTE! Read irc rules before joining to #shells channel.
