I want to be able to logon/logoff to GWIM without sending a
notification that I have come online of gone offline. I know you can
turn off this feature from the opposite perspective. (I can set my
personal GWIM to not display alerts when others come online.) But what
if I do not want others to see me come or go offline. But I want them
to still be able to send me messages. I know if I block a user they do
not see me come or go, but then they can not message me either. Is
there a startup switch or some option that I am missing to disable
this feature?
