Melanie, these are the Delta levels I think reasonably complete, 
for inclusion on the web page. The first level can be marked as done,
as I have done some work on it today and it is practically so. It would be
nice to have these on some sort of web page with a box next to each goal
marked as a tick for done, or empty for not done. (what do you think ?)
