Badges
Badges are sort of like "awards", and the badges you earn are placed into your "badge cabinet" on your user profile. There are many different ways to earn badges. There are some you can get from having x recs, x reviews and x ratings, and the more obscure badges: the ones you can get from just browsing the site!
The following are a list of the badges you can earn. They should be self-explanatory. :)
NB: At the moment, badges are manually given by 
elyaeru. Please message when you are eligible for a badge and you have not yet been given one!
