Simply start Messenger again... just like it actually is explained in the preferences:
quote:
This option allows you to launch as many Messenger clients as you want.
So, that option in Messenger Plus! enables you to start more than one Messenger program, that's all it does.
Without Plus! or without this option being enabled, when you start another Messenger program, the original/already started Messenger program will simply pop up.
With Plus! and this option enabled, a new Messenger program will be launched.
In this new Messenger program you can sign in using
another Windows Live Id than the one you used to sign in in the first one....
----------------------------------------------------
If you are talking about how to sign in with the
same Windows Live Id at two
different places at once (eg: at work and at home with the same Windows Live Id), then that is officially called MPOP
(Multiple Points of Presence).
The feature in Plus! has got nothing todo with this new feature.
But this new feature is not yet available in the current public Messenger versions either. It will most likely be available in the new Messenger version (Windows Live Messenger 9) which will be released around the end of the year....
