Hello,
This is about Manjusha Joshi's question.
Have the following definition somewhere in the beginning.
\def\Max{\mathop{{\rm Max}}}
Now you can use it something like $$\Max_{x\in A} $$.
\mathop is simply one of the class of similar declarations available with
Knuth's original plain TeX.
\mathbin{foo} would cause "foo" to be printed with spaces on either side
as in a "binary" operation symbol such as "+" in a math exepression.
"foo" need not be a single symbol. It can be an expression too.
So one possible way to get two rows of subscripts to the summation symbol
is this:
$$\mathop{ {\sum^\infty_{n=0} }_{n\ \rm even} $$
