I also sent $20 for the effort involved. Premier members can put "view my journal" on their profiles (mine's been viewed 40 times... probably 20 of them m3 :-)) and I get to see that I'm ranked the #1 female in Illinois for mileage (tho' that might be temporary, since another rider has been "on a biking tour" for over a week and might just put in 1000 miles when she returns).
No prizes ('cept that monthly giveaway), it's all "honor system," and I had to discipline myself to stick to progress towards my goal instead of moving ahead in the ranking, which could become a misplaced priority...
and yea, add those miles Gotta get to that goal! about 75,000 miles to go...
