This is a question about Windows Live accounts/security not Windows Live email (since I don't use that) but I can't seem to find any forum that deals with that.

Over the years I have setup multiple Windows Live accounts -- each of which uses a different email address.  The purpose of this was to seperate out various types of interests when using Microsoft forums. 

I just came across the fact that I can have mutiple email addresses associated with the same Windows Live account.

Assume the email accounts are: *** Email address is removed for privacy ***, *** Email address is removed for privacy *** and *** Email address is removed for privacy ***

All of the above accounts are registered seperately in the various collections of Microsoft forums (i.e. Answers, Technet, etc) and have distinct subscriptions.

*** Email address is removed for privacy *** is associated with my identity as a Microsoft Partner.

If I delete Email2 and Email3 from Microsoft Live and then add them to my Email1 account what is the impact on:
1. The individual profiles setup in the various Microsoft forums.  For example, if I use Email2 to log into Microsoft Live and access the Technet forums will I see the activity (points, posts, etc.) associated with Email2 or the activity (points, posts, etc.) associated with Email1.
2. What happens to the subscription settings under each of the email addresses?

My concern is that signing in with an alias will return the same security token as signing in with the primary email address and thus everything associated with the other email addresses will be lost.
