Multi-user Wordpress
While Matt and Co have their own multi-user version of Wordpress, it’s never really been useful to me. Which is a shame, because I’d have like to use it in a number of projects.
However another one called Lyceum has sprung up (an advantage of Open Source Software) which looks like it will suit my needs a lot better - especially as it supports most plugins and themes with few or no changes, something that WPMU doesn’t do at all. edit - Matt has an interesting few points to make about the differences in design between the two efforts, and corrects me on a few things about WordPress MU.
