With DonorDrive, you are able to have notifications (autoresponders in TeamRaiser) sent to participants via text message. This allows participants to quickly see a message such as "Hey John! You just received a $250 donation from Uncle Joe. Be sure to thank Uncle Joe and keep up your great work with fundraising!" This donation would also trigger (with the participant's permission and proper social media linking) an auto-post to Twitter/Facebook that would say something to the effect of "I just received a donation in support of my fundraising efforts for XXXXX. Will you join me in my fight to end cancer? PERSONAL_PAGE_URL". I think this functionality would be a great asset to the system.
