Like other MMOs, some of us want this game to make this happen: being able to craft from guild areas, namely Guild Ships, using donated crafting materials to the guild so all guild can use. So, the guild inventory becomes your inventory, when crafting in guild areas.

Clarification - When, crafting materials are donated, instead of the guild bank, they go into a guild crafting materials inventory. Other MMos have already done this and it's very practical.
