Links Block
This Blocks allows an Administrators to setup links - see the Block top right. But the cool thing is that it can show different links to different users, based on information in their Profile fields! By default it support user fields Institution, City/Town, Department, and Country.
If you have a Login here, and change your Department on your Profile to either IT or HR you will see the links change
