K2 的 forum 搬家了，用的是 Vanilla：Binary Bonsai Forums，搬家的原因在 ATTENTION: New Support Forums! 有提到：
First of all, there have been some complaints over the speed of flickr, and the occasional downtime. This should hopefully be cleared up on BB. And if nothing else, I can now actually do something about it if there's a problem.
Also, there are some forum features I've been wanting to implement, but haven't been able to.
I'll be styling it so it's a bit easier on the eyes as soon as I can find the time (K2 takes priority though).
雖然原來的還是會在，不過看起來整個重心會移過去 :p 那還是現在開始習慣 Vanilla 好了... (對，我還沒習慣)
