# What is the short form of Chemistry Stack Exchange: Chemistry.SE or Chemistry.SX?

In this question the short form Chemistry.SE is used. However the TeX people use TeX.SX (see here). Is it a matter of preference which one to use or is there an official form?

• The TeX guys use it because it rhymes. I don't mind calling Chem.SE as Chex.SX, but I fear that we will become overrun with cereal-lovers in that case. – ManishEarth Aug 29 '13 at 6:19
