User vs ""Chef" vs. Recipes

Hi

Just testet the demo, and what progress.

Just need to understand the relation between eg Chefs and recipes , how is that done, do the user do it by them self or do is it done by the user ID when making new article like recipes.

I have af need for not some fields, and field groups, and an uncomplicated way to post an article. Do you know af good form tool there support article fields and tags etc.

Thanks, in advanced
