Almost all Messenger Plus! preferences and options are already saved and loaded per user account.

But there are some (like the "Multi Accounts/polygamy" and the "Add Messenger Plus! buttons in the toolbar of chat windows") which are saved for all users. Those are called global settings.

Besides those global settings, the bigger features like skinning and scripting are all set for all users at once. That is because of the way they work.

The functions of a script can be coded in such a way that they will only do something when a certain user has signed in (though, the script itself will still run for all accounts).

But for skinning this is not possible since skins alter everything in Messenger, thus also the look of the sign in panel of Messenger. And this panel is shown even before some user has signed in.

It's even so that you always must restart Messenger in order to apply a (different) skin. Therefore, at this moment, it is completely impossible to change skins on-the-fly, thus without restarting Messenger, which would be needed if you want to change skins depending on the user account.

There are ways to force a different skin each time you start Messenger, but that involves copying files and editing the registry each time and before you actually start Messenger, by starting up Messenger with different shortcuts. But even then, it will not be user specific; The skin would still be applied for all user accounts.


EDIT: can be done without involving reg edits apparently, see the link Spunky posted.
