After you click on race space it goes to your profile, then at the top click on search profiles and there will be a spot to type in thier user name. Hope this helps.
Be careful as many of these are Phishing expeditions. Sending you to a website to get your email addy and/or a backdoor way into your puter. I get gobs of these every single time I post a new listing on Craigs List. I know they are phishing cuz I list my phone number and note that I do NOT answer email inquiries. Once you answer THEIR 'inquiry', YOUR email addy shows up on YOUR answer to them. NOT as secure as CL says they are........
