When your team captain posts miles, I suggest the following format to make things easier.
Title of post: Team Name Week X
Participant W: X miles
Participant X: X miles
Participant Y: X miles
Participant Z: X miles
Total miles: X miles
Total virtual miles: X*10 miles.
Also in the labels, put your team name and the week number so we can easily search through them.
Let me know if you have questions!
