Sending PMs by script? Editing player chat bar?

[Admins]

If you want to send a pm directly to another client then you will need to use a GuiPMEditCtrl. This is to make sure the player is editing the text, scripts don't have access to the text of that Gui control.
If it's possible to manipulate the default chatbar then we will need to add a protection against that.
It wouldn't be good if scripts could send PMs in the name of the player, or send chat messages in the name of the player. Sometimes security is better than functionality. There are also reasons why the scripted RC doesn't have the same functionality like external RC yet.
