testing the tires
Well, seeing as how I manage my own WPMU install at Talk Islam, I must say I approve of the switch in principle. Still, losing all my user history, comments, posts, diaries, etc seems a pretty stiff price to have paid. I guess I should be thankful that my username was preserved, at least.
Neil or whoever else is doing the needful around here – I wrote a WPMU plugin you may be interested in using.
