I haven't looked at the code yet but I have some suggestions for the functionality.

• We should have a new Voice Chat that's more descriptive on "hey you're about to create a new voice channel". Maybe something like "New Voice Channel" instead of using Chit Chat.
• The new room should be based on the "creators" name e.g. "Christolis's Room" and it should automatically move you from the "New Voice Channel" to "Christolis's Room" (people can rename after as needed)
• We should have a cleanup task e.g. if a voice channel has been empty for 5 minutes then it should be deleted.

Importantly, the existing channels should be protected from the changes that get implemented here.

This is just an IMO - we should wait for further feedback first.

I love @tj-wazei suggestions, we shouldnt delete channels immediately and one more thing to add. We also wanna cap channel count to a certain limit. For example we can't have more than say 3 channels per category for now. We can put this limit in configuration so it's easily tweaked without making changes to code by maintainers.
