Legacy's subscription allows a friend list with 20 spaces to put names on. Here is an example of a friends list:
The names in gray are offline and the right hand column will tell you how long for e.g NaziHalo offline for 715 hours. If you add a Staff member as a friend it will say Unknown , for example, Vader.
All names in white are online and it will tell you what page they are looking at, at the time. The names in blue are in Online Chat. For example, Tsukasa. to view who has added you as a friend click "[View]" and it will give you a list like this:
Remember, you need to buy Subscription to get a friends list on Legacy.
