You need Crowns to level up and you also exchange them for glam items.
There are things for all of the Playdom Games not just SL.
As you level up different glam items 「unlock」.
You can get crowns from sending free gifts to ur friends but these don't appear to help u level up.
According to the FAQ you get Crowns when you purchase Brownie Points (and creadis in other Playdom Games). I assume that when you earn these Crowns they will count towards leveling you up.
They currently show 9 different glam items. 6 unlock when you join.
I figure out how to get more crowns by using request links.
Now you can claim all my links below to get more crowns.
(somehow few of them may be able to reclaim up & some of links may not works)
