If you have any problem with me or want to contact me privately for some reasons, you can email me, at
vuvandungchelsea at gmail dot com. However, if you have (La)TeX questions, please don't email! Ask a question here is the best option in that situation, because note that I don't have the sufficient LaTeX knowledge to answer such questions, and I don't check my inbox regularly.
