Xobni (it’s inbox backwards) is an add-on for Microsoft Outlook which shows the hidden social network in your inbox.
Xobni adds a sidebar to your outlook and automatically tracks your contacts and organizes the messages in to threaded conversations. It adds a profile for each of your contacts, conversations you had with them, and the file exchanged between both of you.
It is quite good tool if you use outlook alot for your email management. This is currently in private beta, i am using it for quite sometime now and i am really impressed with it.
5 invites to Xobni, drop a comment if any one of you are interested to have one.
