Well if it is pure HTML such as table, form and iframe, you can always use this syntax in PHP to convert HTML to PHP string:
PHP Code:
$article_content .= "html text in it, can be letters, numbers, tables, forms...";
Nonetheless, this wont work with javascript. I do believe theres a way to get Javascript to work with Mys, and it shouldnt be hard at all. Anyway this script so far is an enhanced version of MA, although we are diverging fast from the shell of Rusnak Adoptables. If javascript works on MA theres no way it wont work with Mys.
