Forums Scripts & Popups Link certain text to other channel

Hey

I have no clue how to fix this script:
When a certain person writes a certain text/ or a part of a sentence like = <Notice!> then the rest of the sentence comes) it automatically links that message to another channel that I am in.

How do I do that?

;;Edit
And is it possible to highlight all the users in that channel before the quote of the message from the other channel is displayed
