The new automatic stats (alpha test):

All members:

This displays the share of users that participate in each project of all members in our member database. Some do not participate in any project at all, to our knowledge, some are not members of our team at the projects.

Fullblown members only:

This displays the share of fullblown members that participate in each project. Fullblown members means members that are a member of our team at every project they participate in (and NOT that they participate in all projects).
