I was recently asked what version of Wordpress is Wordpress MU based on. Is it based on the latest version of WP single user to operate? or is it based on a previous version?
After installing both the single user and multi-user, it looked exactly the same on the admin side, so I figure it had to be the latest. As well, security fixes and vulnerabilities would be a key issue in any multi-user platform, and having MU based on a previous (and less secure) Wordpress installation would be ludicrous.....but after much searching I couldn't find a concrete answer.
I'd also like to say I'm quite a newb to the Wordpress MU scene, but I think it's a fantastic platform with a lot of dedicated users contributing to its growth. I get a good vibe here :)
