I have had a play with MSN and have come up with the following codes:
\me 43-----
3
A Message in MSN Green
43 -----
\me 43-----
5
A Message in MSN Red
43 -----
\me 43-----
43
A Message in MSN Grey
43 -----
The only problem is, that is requires you to set your name to ALT 0160.
I propose that someone make a command that can send those Plus! 3 Messages by typing something like /msnredmsg <your message>, etc, but without it including (ignoring) the MSN Nickname.
I made the code from this predifined code:
\me 43-----
43
The following message could not be delivered to all recipients:
5
<User Message>
43 -----
NOTE: Perhaps this can be incorporated into the Away messages.
\me 43-----
43
This user is away because of the following reason:
5
<away message>
43 -----
I have attached a CE that may be needed for some of the errors.
And Finally, please treat the \ before me as /
EDIT: Post Fixed, thanks for telling me.
