Yes, I know many people try to write some packages for typesetting chemical formulae for inorganic and organic but, they seem to be difficult to use, some of them can typeset organic ring but not easy to locate the picture at the position that you desire. And another disadvantage of chemistry packages is the syntax too complicated for users, even me. You've done a wonderful work to help people insert some simple ones into this forum.

[math] \ce{Zn^2+ <=>[\ce{+ 2OH-}][\ce{+ 2H+}] {\underset{\text{Hydroxide trong khong khi}}{\ce{Zn(OH)2 v}}} %group! <=>C[+2OH-][{+ 2H+}] {\underset{\text{Hydroxozikat}}{\cf{[Zn(OH)4]^2-}}}% group! } [/math] I've just typed some vietnamese words into the quote mode to show my friend how mhchem work in PHP, so this is an example for our admin to install this package in our chemistry club forum. So if you know how to install LaTeX render in ASP please help us. Thanks in advance In the mhchem manual I dont see any code for typeset organic ring formulae. Is this a disadvance of mhchem package?

To typeset chemical formulae directly into your PHP forum you have to install LaTeX render for php with asmath package, and your server have to have Linux OS installed. To typeset chemical formulae with LaTeX you can combine PPCHTeX, XymTeX, any many more. You dont tell user how to typeset their desire formulae. I am writing a book about typesetting chemical formulae with LaTeX, if someone interested please let me know.
