Its good to have another Minnesotan on the site. Laramie is great and Hamilton is cool, but MN is really the orienteering Mecca of North America :)
One thing you should do is show up to a Minnesota Orienteering Club meet
www.mnoc.org. There is a skills training day March 25th at Hyland in Bloomington which as a skier I am sure you are familiar with.
As far as this website and log, it is very straightforward and intuitive.
