This is really a pretty simple tip but very handy at times. I guess it’s the equivalent of adding a speed dial to a telephone.
Type a phone number in the Search box, and then drag the number from the Search Results box into a group in your Contact List.
Another nice thing about this feature is you can start a conference call with these numbers when you place them in a group by right mouse click on the group and selecting start a conference call.
You would be surprised at just how many people don’t know you can do this.
