Do something elegant with Bump URLs that lack {you} tags?

[calroc]

If we allow Bump URLs of the form http://dendritenetwork.com/bump/{me}/{it}/ leaving off the recipients' tags we could do something elegant with them when people browse to them.

• If the visitor has used the site before and has an ID tag in their cookie (see Store own ID tag in cookie #2) we can just add their tag to the end of the URL and jump to that triggering a normal "bump" event.
• The the visitor is new we can display the bump page but with extra content to help them figure out what's going on and participate if they want to (although you should never forward a Bump URL to someone without first contacting them some other way. Remember that you're normally only exchanging bump urls with contacts you already know and who are already in the DN system.)
