+    Not Subscribed to Groups table should be clickable. Let's briefly
+    now consider the other columns of either the Groups List or not
+    Subscribed to Groups table. The Name column gives the name of the
+    group. Group name are unique identifiers for a group on a Yioop
+    system. In the Groups List table the name is clickable and takes you
+    to the <a href="#group-feeds">group feed</a> for that group. The
+    owner column gives that username of the owner of the group. If you
+    are the root account or if you are the owner of the group, then this
+    field should be a clickable link that take you to the following form:</p>
+    <img src='resources/TransferGroup.png' alt='The Transfer Group form'/>
+    <p>that can be used to transfer the ownership of a group. The next
+    two column give the register and access information for the group.
+    If you are the owner of the group these will be dropdowns allow you
+    to change these settings. We have already explained what the Join link
+    does in the actions column. Other links which can appear in the actions
+    column are Unsubscribe, which let's you leave a group which you have
+    joined but are not the owner of; Delete, which, if you are the owner
+    of a group, let's you delete the group, its feed, and all its wiki
+    pages; and Edit, which displays the following form:</p>
 <img src='resources/EditGroup.png' alt='The Edit Group form'/>
-    <p></p>
-<img src='resources/TransferGroup.png' alt='The Transfer Group form'/>
-    <p></p>
+    <p>The Register and Access dropdown let's one modify the
+    registration and group access properties for the group which we have already
+    described before. Next to the Members table header is a link with
+    the number of current memebers of the group. Clicking this link expands
+    this area into a listing of users in the group as seen above. This allows
+    one to change access of different members to the group, for example,
+    approving a join request or banning a user. It also allows one to delete
+    a member from a group. Beneath the user listing is a link which can
+    take one to a form to invite more users.</p>
