I found an addon that has been abandoned by the Auther called Deposit Box 3. http://www.wowinterface.com/downloads/info22465-DepositBox3.html I would like to try to revive it. But when I add it to the addon folder with all my other addons it does not show up in the wow client. I tried adding it to the ptr addon folder. The add-on button does not show up. Any ideas on how to fix that issue?
