Welcome Eva, thanks for your post.
We started a poll. You can vote if you want two different colours, for being in room and just using zz button. Tell your friends to vote too please.
Do everything to get as many members as possible to vote - talk in game, change your banner, advertise in room ;D
More important for me would be to be able to be "busy for all users but friends, lovers and spouse"
Could be one button for all, or separate ones for each category. This way I would be sure not to get bothered by "strangers" while I'm chatting with my friends.
