[Request/Is this possible] Multiple Chat Channels through the API?

I've seen it discussed a few times and it's something pretty much everyone I know who uses R20 would want in. Is it even possible, through the API, to modify the UI of Roll20 to allow this? Or would this require a change by the actual devs?

Theoretically you could create a script that could take a command with a message and then re-whisper the message to the predefined players. The api cannot change the Roll20 UI though.

It would be possible to create something that behaves like this, yes.  It's actually on my list, but far down. =D Most people simulate this by having characters named after the channel (say Guild) and then /w whisper them messages: /w Guild Hey Guildies, how's it going? Then you just put whomever should be in that channel on the controlled by line and you're done. Many people use that same technique for languages.  (Elven, Dwarven, etc)

I'd tried that alternative you provided Aaron, but the issue is that I'd have to individually add everyone into, what I'd basically like to be, the OOC chat. Since we have a fluxuating amount of players, it's a bit clunky.

Hmm.  Can you go into more detail about how you would like it to work?  And expand on the difficulties with your fluctuating players (that's players, not characters, right?).  At a minimum, I can probably get you a simple script that will make it easier to set things up.
