It's been two weeks since we launched Tungle and already, we are seeing some interesting trends.  We are glad to see small groups of five or six users within one company signing up to use Tungle to share free/busy calendar data.  This is great news as we believe in Dynamic Availability (http://blog.tungle.com/tungleblog/2008/04/we-are-live.html)- and real-time calendar sharing between trusted colleagues is an important component in solving the meeting coordination pain.

If you haven't tried it yet, here's how easy it is to use Tungle to share calendars with anyone, inside or outside your company environment:

1. Find the user in your contact list.  You can use the filter box to quickly find him/her.
2. Mouse over the name, and a share button will appear.  Click on it.
3. On the popup, you can ask your contact to share his/her free/busy calendar with you and you can decide whether you want to share your calendar with him/her.  You can have different sharing combination for each of your contacts.

You are done.  If your contact already has Tungle installed   they will get a popup with your sharing request.  If the user is not a Tungle user, then they will get a nice email from you, inviting them to get Tungle.  Once they are sharing, the icon next to their name will turn purple and instantly, you will be able to see their free/busy.

Try it, it's easy, and it works.  Let me know how you like it.

P.S. If you are already using Microsoft Exchange to share calendars within your enterprise, Tungle will act as your personal Exchange outside the office.  Tungle is fully compatible with Exchange and enables you to share calendars with partners or friends outside of your company.
