I have installed WP 3.0.1 and enabled multisite.
I installed a few plugins and then created a subsite. My site is going to be a one administrator for all sites (without any users getting the ability to register).
I found that the subsites don't inherit the theme or plugins (which is good I guess). However, in my case, it is better if they share the theme as well as plugins. I looked around a bit (searched the forum here too but found none.. maybe wrong search terms) and found something called WP Hive (wp-hive.com). Looks like the thing I was searching for.
Is this the accepted way to do it or is there a better way to do it? I am new to WP, so have been going up and down the menus, but haven't found it yet :)
