I thought of an idea for the shoutbox, add a time on the very right hand side of where the message is.
This could help so people know if the shoutbox is occupied or not.
It isn't really necessary but could be helpful to some
Heres an example.
[SHOUTBOX]
friendly_man: hello [13:52]
random guy: hello [13:52]
That isn't very realistic but I have no skills in editing so im not gonna edit a screenshot :P
