I've been looking at things like the Comedy Club in General Discussion, and things like Blockoworld, and thought it might be helpful to have some way to visually set aside chat from admins or somebody taking a stage...
Basically, my thought is this: regular chat is moved halfway down the screen, and the "speaker" chat occupies the top half. Also, instead of splitting it to admin and non/admin, you could use an onPlayerTouch or an onActivate event to select the "speaker." That way, anybody taking a stage or walking up to a podium would get their chat into the top box without having to be admin'ed.
