Not sure but i think hes saying that his Internet connection fails and that is whats causing the problem. So he is wanting to join with his normal nick but it hasnt pinged out yet.
There is a Ghost command supported by most networks.
/msg Nickserv GHOST "The Nick You Want to Recover" "Password of That Nick"
That will reclaim that nick, you could also use something like .
raw 433:*:{ .msg Nickserv Ghost $2 "Password" }
That would work if you put it into your remotes. What its doing is when you get this message "Nickname is already in use." it runs the Ghost command. Downfall to that is that your password is in the Remotes.
