Contacts in Skype are just like in any other program. You might have a bunch of friends from school and some others who don't have everyone in their list. Skype allows you to forward these contacts to others. Select Tools > Send Contacts. Hold down [Ctrl] and click on the contacts you want to send. In the Send low contact to whom you want to send the list. Click Send.

The other interesting feature people usually miss out on is Groups. Go to View> Contact Groups > Enable Contact Groups. In the small Groupsbarthatappean
click on the + icon to crea te a new group. You can now drag and drop existing contacts from your list into any of these groups.

The Groups feature allows for flexibility. For example, you can right click on a group, say all your colleagues, and click Start Group Chat. You can also send contacts and files (like we mentioned).
