Good idea.Many times, i want to lead people get togther and talk about anything we want to say,but you know ,we feel the lack of an efficient way of doing that. 
by the way,today is Christmas day,i hope all our friends can enjoy a nice day. 
Hey guys, Happy Birthday!Merry Christmas and Happy New Year!
I always like this kind of coincidence–to celebrate festivals and birthday at the same time! The festive atmosphere makes you feel like the whole world is celebrating your birthday as well.
It’s great to be a member of the big family here in Seeed Studio! Always full of cheerfulness, happiness and fun!
