Knoeki,
The main reason the channel count is gonna be off
is the use of the $comchan indentifier.

Total user count is gonna be off sometimes because
it will count users more than once if they are in
more than one of your channels and at the very least
could be counted easier with the $ial identifier.

All of this can be accomplished without the need for
/set and /unset %varibles to eliminate harddrive writes.

btw: $network and $server are not the same thing.
$network may have more than one $server and some
$network may allow more than one connection.
also (unfortunately) $network and $server DO NOT
have to be unique names on the planet.
The DOMAIN name MUST be unique and so must $serverip
BUT unfortunately $network and $server are sent out
by the server in the raw 001-005 lines during connect and
can be anything they set it to. This is sorta off topic
but this means if you ever write like an auto-ident to
NickServ/ChanServ maybe better to use $serverip for security.
