I've discovered gridreplublic through BOINC.

About having a more active community. I think thats a good goal because no one has more interest in keeping things updated and with a fresh feeling has the users motivated to contribute. For example, most projects page seem outdated and some projects have even ended but it's not easy to see that or the results obtained. Being hable to keep the information about each project updated and results/statistics at hand would be very nice!
