User Id's missing in 3.1

I suppose you could write a plugin to put ’em back in if you really wanted to, but they didn’t serve much purpose to most users, that I’m aware of.

The NUMBER was always arbitrary, so it just confused people. And we had numerous people (OCD like me) who itched and wanted to see them all in a nice order, 1-2-3 etc. But when you deleted one, BOOM, they went awry.

The primary thing site ID’s help in is associating the directory in blogs.dir with the site. Having that info handy is helpful in my opinion.

This is the work of about 45 minutes (much of which was teaching my mom about Twitter).

Toss it in mu-plugins and use at your own risk. No, you cannot sort by ID.
