Poke can be forward to your friends now! When you receive a special poke from others and want to send to others, just clicking the “Forward” button which under “Mirror back”, then choose your friends, they will get your greeting.

Nov/3
New “saying” with URL support (available on the mobile only). Input any website URL you want to share with your friends, it will become a link (blue color, underline) automatically. For example: http://www.morange.com
