TOPIC: how can i redirect after payment is submitted?

after payment is submitted, I'd like users to move to another page — a component page link that has a tell-a-friend form so they can share with friends that they've just made a donation. would be way cool. Is this possible?

if not, can I add a hyperlink on the thank you page? Instead of just saying "thank you", maybe it could say "thank you... please tell your friends of your donation and invite them to do the same."
