Feature Request: message all rooms for announcements

[kacycrider]

I’m interested in seeing how it would work to message all rooms at once. This would be useful for announcements and updates and giveaways.

It’d be neat for the message to look differently than other surrounding text.

I imagine it would take the following steps:

Admin only access— subdomain then authentication?

Links all Jitsi rooms together

Message all rooms

Format the text per the theme

Likely many other things
