I've been going through the Argosoft supplied web templates and have been surprised to find a number of structural problems with the HTML. Mainly I've found improperly nested tags such as:
[body]
[form]
[/body]
[/form]
(I've substituted the square brackets for the customary less-than and greater-than tag delimiters to keep the forum software from choking on it.)
The templates work, but I suspect that that's only because the browser manages to figure out the intent and fixes it on-the-fly.
Take a look at the templates and format them with proper indentation and nesting and you'll find a number of problems.
Just an FYI.
