Suggestion

I know Spencer already told everyone how to post their points, but it's hard to tell who has updated theirs for the week and who hasn't. What would you think of this solution?

Each week, someone makes a post with the title Week 1 (2, 3, etc.) and lists everyone's names. When you enter your points for the week, you put your weekly points in the corresponding post. (Since everyone is an administrator, everyone should be able to go in and edit posts - ask me if you don't know how to do this.) Then, you simply put your total in the sidebar, possibly with the date (as Lisa has done) so everyone knows when the total was last updated. That way, you can search to see individual weeks if you are interested, and it would be easy to see who hasn't entered their points yet because their name would be blank in the Week 3 (or whatever number) post.

With the faith (ha!) that everyone will at least be willing to try this way for a week, I will go ahead and make the Week 3 post so you can see what I mean.
