HOW TO RESTRICT MEMBERS FROM GUILD STASH

Hi, I recently made a guild with 1 friend and was hoping to expand to more people. However my fear is that people will take items out of stash and leave guild. How do I restrict access to members? I have checked many sites and almost no relevant information is to be found. The only info I can find is people complaining they have no access to guild stash. I have 3 ranks, Me the leader, Officer, and members. I invited someone and told them to try and take something out to test the stash and they could take out whatever they wanted so I kicked him until such time I can figure out how to restrict the stash safely.

Thanks in advance for answers/replies.

Right click your guild stash tab header. It lets you set permissions by tab.
