It is easier to play when you have a clique. They will send you gifts and they will help you unlock shops, fly to Vegas, collect requests for specific boyfriends, vouch for you, etc. One is advised to do likewise for your friends.
If none from your current facebook friends are It Girl players, you can always request to be added to friends and as a result to a clique (and increasing your own) on the official forum thread here .
You can also add people yourself from this forum.
The quickest way is to add those who have posted their requests last in ther forum. For this check the last pages of the forum.
