Email web of trust - wiki added

I put up a wiki for this topic with some items from the summary that 
Peter posted to the list. Feel free to update the Wiki at your pleasure. 
Note however, that I probably will not have time to update it as 
discussions go on, so it would be useful if someone decides to volunteer 
for that role.

The wiki can be found here:
