Hey,
Thanks for the reply.

Say I'm on a server as The_Turk, and then at Uni I log in via my laptop as StevieT. I'm wanting to PM The_Turk saying !invite then channel and it'll join that channel without the need to /invite The_Turk #channel - like taking a part of text, putting it in a script, and then executing.
I hope I'm clear enough. =]
