hello ^^'

At your service.

First, go to the Admin Area at the top of the group page. Next, click "Manage Members" Go down to "members" on the right colum there is "Oh Home, Members" below that is the box about join requests. Click either "Are automatically approved" or "Are subject to vote"

Opening folders is done by scrolling down farther. Go to "show all folders" and you are able to organize it from there.

A lot of things are self explanatory, just browse through the settings and you should be able to place everything as you want it. c:
