/msg $C CSUSPEND <#channel> [!]<duration> <reason>
This command will temporarily remove $b$C$b from a channel and suspend its registration.
The duration may be "0" to make it never expire; otherwise, $C will automatically unsuspend the channel after $uduration$u.
If you wish to modify a currently existing suspension, add a ! before the duration.
