Hi Cynthia. Even though I just got started in my fundraising efforts, I have already found these sites to be useful.  I have yet to send out my donation request emails or letters, but have already received some donations from friends who found the link to my Team in Training page on my myspace & facebook sites.  Another easy way to get people onto your fundraising site is by posting a myspace bulletin with your info and web address & asking all of your friends to re-post it.
