export/view user id

logged in as site admin when I go to Blogs the blog id is listed next to each blog. But in Users the user id is not listed - is there a way of viewing the user id or better yet a way of exporting this info out of wpmu in a txt file?

Using Reveal ids plugin found here :

but doesn't seem to assist the site admin pages.

thanks
