User:Tsui
Since my knowledge of the English language is limited, I am only contributing minor edits, inter-wiki links and images here. I'm more active at de.wikipedia (User:Tsui) and Commons (User:Tsui).
If you want to get in contact with me I recommend to use my talk page at de:Benutzer Diskussion:Tsui or commons:User talk:Tsui which I check for messages daily. Or, if logged in, send an e-mail via E-mail this user in the menu.
