The default Blizzard Guild interface doesn't share information about Cooking skill and recipes among guildmates.
This addon allows you to share all the Legion Cooking Recipes with your guildmate.
It uses Ace3-Comm to share informations about discovered recipes and your current rank. Your guildmates need to have NoNameNoFood installed to see your Cooking recipes, and for you to be able to see theirs.
Usage : type /nnnf to open the recipe interface
