Usage: `/FINDHOST [channel|ALL] userhost'
With this command you can search for a user using a userhost pattern. AmIRC will return all users matching the pattern on the currently active channel. Alternatively you can specify which channel will be searched in. With the ALL argument you can search the entire network.
Examples:
`/FINDHOST *.vapor.com'
Will list all users at the VAPOR.COM domain on the currently
active channel.
`/FINDHOST #Amiga *.vapor.com'
Shows all users at the VAPOR.COM domain on #AMIGA.
`/FINDHOST all *.com'
Shows all users at the .COM domain on the network.
