I think that this is a great idea. However I think your instructions are a little confusing. Here is what I got from it please correct me if I am wrong.
Step 1. Write a post with:
a. My name
b. The number of books I plan to photoread this week
c. The number I need to photoread each day to reach my weekly goal
Step 2. Write a post daily including:
a. Name
b. list of book titles I photoread
c. Add smilies so everyone knows which day of the week it is
Is this right? Also I was wondering if you wanted to have everyone running their own weeks. So since today is day thursday my day 1 would be on thursday or if you want to have everyone's week start on the same day ie. sunday or monday.
