Shoutbox

I am a newbie here, but it seems that using the functionality to change text attributes and send sounds only works if the other contact is using MSGR Plus.  If not, they just see little boxes within the text. 

Is that true, that I need to get my contacts to use Msgr + for many of these features to work?

Also, is there a way to stop teenagers from using some of these functions?

Okedokies welcome to the forums

Both contacts do need Plus! for colour etc
Not all the features are Plus! required but some are yes.
What functions would you like to stop?
