In the top left corner of the screen is a small [+] button; tap it.
Type in the username of the user to be added. Be sure to type in the exact username of the person to be added, including capital letters, numbers, and symbols. Note: Multiple usernames can be added in this section to make adding lots of friends at once easier.
Players can personalize the request message by tapping on the message box.
Lastly, tap the "Send" button in the top right corner of the page.
To visit a friend's park, click on the "Social" button at the bottom of the screen in DragonVale. After doing so, click on the friends section, then simply tap the "Visit" button next to the friend whose park is to be visited.
On June 7, 2013, the "Friends" icon was modified.
On June 14, 2013, the "Friends" icon changed back to the original icon but was reverted to the newer icon on June 17, 2013.
On June 27, 2013, the Friends menu changed to Social menu with the addition of "Gifts" and "News" section. "Friends" is now a section of the Social menu.
Previously, if more than four people sent a gem to a player while the player was away, only four names would appear while entering DragonVale; any remaining gems were grouped as "others". With the update to the Social section, gifts are all listed and can be collected from the new section.
The icon to open the menu to see a player's list of friends has changed three times.
The first icon of the hooded person was a part of DragonVale at the beginning of the game, and has only been linked to the menu as the Friends Menu.
The second icon with one black head and one white head became available while the menu was still the Friends Menu, but transitioned with the name change.
The third icon with two white heads has only been available since players have gone through the Social Menu to see their friends list.
If after the 24-hour period the gems have not replenished (the gift option is greyed out), try restarting the DragonVale application.
