I'm interested in becoming a TU.
I used Arch only for one year and a half but 4 for Linux (Ubuntu before). I submitted my first package by the end of last year, and maintain more and more during the last a few months. I am eager to maintain packages that loved and needed by Chinese users as I am one too, such as input methods(fcitx-*, ibus-*, sunpinyin, libpinyin, etc), internet supplicant in Chinese universities(mentohust/ruijieclient), chat tools qq related(linuxqq, webqq, libqq*, etc) and popular proxy tools (sshuttle, goagent, etc). And I am also a python programmer and maintaining more than 20 python libraries I use for now. I am also active in reporting and following issues upstream, such as pidgin-lwqq .
As I looked after more and more packages on AUR I found many users not so convenient to install so many packages in AUR, so I joined archlinuxcn's community repository project  to provide popular packages in binary. But this is not good for user to involve in (such as flag out-of-date, report bugs, etc).
I am also an IT manager in work, and maintaining several Arch servers.
Some more info about me: 21, male, Wuhan in China, working in a startup, not very good at C and English.
