Make notes for each day able to be entered withouta title since you cant post multple notes per day

Also the interface is cumbersome

Perhaps a textbox instead of going thru the whole forum-style type of entry

Also, have you considered having the daily summary / entry a page that allows entering of all data? The less clicks, the less time, the more user friendly.

I like the PLAN system. I don't like the interface.. my 2 cents
