I have a suggestion. Why not create perma-links, so someone trying to sell his account could put a link to his analysis in his signature ?
There are Permalinks, kinda. Under the token there is a link for "Share this estimate" and that will link back to the estimate once it generates. The estimate only stays on the server for a week though so that link will only work for one week. This is so that storing the estimates doesn't crash my server.
