LINKTO :host:port
------------------
Establishes a new link to another bouncer. You can link as
many bouncers as you wish. That won't slow them down. Then you can also chat 
in Bouncer PartyLine or in the bouncer channel. Users from other bouncers 
won't have access or rights in your bouncer !
Example: 
/linkto :this.is.host.of. bouncer.that.you.are.linking.to.com:54321 
Your bouncer (host and port) must be added in the bouncer that you are linking 
to in order for this connection to work.
