After installing ubuntu 10.10 on my computer, I found that SCIM is gone!
I already used to installing boshiamy input in SCIM every time i re-install linux OS on my computers. This time, I should find another way around. The following website is what I found to help me resolve this problem. Basically, it's much easier than what I've done for having Boshiamy work on SCIM. I just need to install a package and select the input method in the configuration UI! Well, let's call it IMPROVEMENT.
Well, til now, I still don't know why SCIM is removed from 10.10..
