Few things I've noticed here;
One, some members have not validated their CPIDs. This is required for your points to count towards the Sprints and Marathon points here. All members of the team who wish to participate must register and confirm their CPID.
Secondly, teams who join BOINC Games after an active Sprint is on-going will not count towards the current Sprint; but will be included in the next Sprint that starts.
Last but not least, the last hourly update is all big fat 0s. I am not 100% sure why and I am hoping the next update will have some positive numbers for teams participating in this Sprint. I took a look at the Cosmology site/server and it doesn't seem to be down or effected by the few members who are participating.
