I have a question and I was not to sure which topic to ask this under, so forgive me Willy if chose poorly.

On most of the projects when you go to your account or profile there is a list of "Projects in which you are participating"

Where does this list come from? Does it come from one of the stat sites? Who maintains it?

It comes from http://boinc.netsoft-online.com/, for example this is the file with your stats.
