So sorry that I read your email until today.
Due to the huge amounts of spam subscription request, I have to manually
sort the unknown/suspicious addresses and put them to the banned list. I am
sorry that I mistakenly put your address to the banned list. Now you are
joined the Simplified Chinese translation mailing list.
Hope you can post a self-introduction there too.
For translation, I recommend you to read these guides first.[1,2]
See you in Simplified Chinese translation list soon.
