If you're not from the USA:
Either go to:
and log into Stardoll for the earrings.
and log into Stardoll for the stickers.
Or while you have the manual proxy set to join the Dove club (see 2 posts down), go to:
http://www.stardoll.com/en/contest/finish.php?id=784 for the earrings and
http://www.stardoll.com/en/campaigns/spinbrush/ for the stickers while the proxy is on (and isn't too slow).
