Boys and girls this looks really cool! I'm not totally sure I know what "badges" means, but I think I grasp the overall concept, which is: "Don't just tell me how to do it, show me!" This has always been my approach with regards to foraging. :-)

While reading the original post, I also had a thought about how to make this program more inclusive... Perhaps instead of worrying about segmenting it to fit different demographics (hunters, fisherman, vegans, unicorns, etc.) you could just add little symbols next to various categories, which will let folks know who this sections is geared toward. For example, while the category of: "Hunting" might only be suitable for hunters (H), the Edible Garden Weeds section might be perfect for hunters (H), vegans (V), health nuts (HN), etc., etc.
...Just my two cents...
I hope I'm not WAY off base.
Warmly,
