I'm currently developing a free course in Norwegian. It is a rather slow process, but more content will gradually be released until I'm finished with all of level A1 (First of Two basic levels).
The link for the site with PDFs for extra material: Norwegian Course.
Currently there are no way for you to give feedback. However, feedback will be appreciated and I will soon create more opportunities for 2-way interaction in the above mentioned site where the course will be developed.
Another update: If you are looking for a real cool Norwegian dictionary that will show you the conjugations of both Nouns, verbs and adjectives: Norwegian Dictionary
