many thanks for your quick response. i sent the three emails from the sparkpeople site (help, customer support, send email), all within the past two months. i think i have finally figured out the answer to my first two queries, but here is my latest (sent last week, i believe). can you only sign up for one virtual race per given week? i wanted to track two 5ks for this week, but i can only figure out how to sign on for/track one. please advise. i look forward to hearing from you. again, many thanks for your time and effort and for the effort of everyone who makes sparkpeople an indispensable site.
