Earn XP for search, recipe completion etc.

[andrasfuchs]

Every user should be able to earn XP and level up if they use the site. XP comes from searches, ratings, recipe completion, pozitive responses from the users who ate your food, friend registration etc.
Tip'n'tricks could change depending on the advancement of the user.

All the features should be switched on/off depending on the XP level of the user.

Let's say the following:
Level 1 features should be basic search, basic profile settings and showing directions without equipment and nutrition ifnormation.

Level 2 is weight, height, age information on profile screen, personalized portions, and negative search.

and so on....

On the other hand, all users should be able to turn features on and off manually on the settings page. Settings page should also have links to the help page to explain the features in detail.
