linux_pro,

> i think this group speak chinese,why not use ?
On a mailing list people tend to really follow the conversation, so
it makes sense to stick to one language on a mailing list.

Unlike for example in a 'planet' aggregation where I think it's cool
to see what's going on even in languages one doesn't understand, especially
since blogs tend do have pictures, videos, etc.
But mailing lists don't, they are very text-based.
We actually have a (very quiet) Spanish mailing list, it would be easy
to open up a Chinese-speaking mailing list.

Xiangfu, should we do that?
