Site list, user list

What about that plugin didn’t work?

You could try something like this: http://codex.wordpress.org/WPMU_List_All_Blogs_Widget

Or, if you know PHP, you can create your own plugin to do it. Doesn’t look like there is much out there to do a publicly facing list.

The plugin just listed the main domain. Any other site isnt’ listed

are the other sites marked as private? Cuz that’ll prevent them from showing.
