Hi all,
I encountered a unknown user in my Google Docs shared users list. I don't know that person and I can access a shared spreadsheet from this user as well. I searched my address book but the email of this user is unknown to me.
Does anybody else see this too?

Thanks
Andy

What is the url?

Here it is:

Yes, I have exactly the same issue. Lots people I don't even recognize are in my "Shared with..." list. No docs show up when I click on the names, even though it shows anywhere from 1-7 docs available for each.

I simply deleted all the docs and now all the people are gone from my list.
