Sending PMs by script? Editing player chat bar?

[jake13jake]

Okay, I have a few ideas to improve how players communicate to each other that I'd like to let the players on Classic have access to.

My questions are:
1. How do you send a pm/guild/mass message by script?
2. Are there any event handlers in the chat bar that would allow direct editing to the chat bar? (if there aren't this is going straight to future improvements)
