I think there are some fundamentals being missed here, given that this member has assumed the title of "Microsoft Legal".
First off, I'm not a lawyer, but have had a lot of experience with them. Here are my opinions, and they are my *opinions* only:
1) If this person is a bona fide representative of Microsoft, then I would have thought that he/she would have contacted the owner of this site before registering. Remember my first sentence above.
2) The first post was really against the rules here; as innocent as it was, but it doesn't inspire credibility.
3) There should be a very clear signature as to how this person speaks, or purports to speak for Microsoft. That would have been my very first priority.
To sum up, and I'm not trying to be pedantic, but this new membership should have been thought out more professionally from the get-go.
