This question is inspired by my arguably perceived perception about a confusion at least among younger crowd about $\LaTeX$. $\LaTeX$ is just a set of macros for computer typesetting system $\TeX$ developed by Leslie Lamport. Even though it is now almost a standard set of macros in mathematics publishing, it is wrong to assume that there were no other no less useful $\TeX$ macros for writing mathematics. The first one that comes to my mind is AMS-$\TeX$ macro package developed by Michael Spivak and described in his wonderful book "Joy of $\TeX$".
I was wondering if people can name mathematics Journals which accept submissions written by $\TeX$ macros other than $\LaTeX$ or in pure $\TeX$ for that matter.
