concerning the second problem I can suggest two ways

• If you can use unique names for you LOOPs in a html, then you may use global vars like "SOMENAME_REVERSED" in the begin of html not inside of deep structures
• If your LOOPs are not huge then you may provide the both direct and reversed representations of the list for each LOOP. e.g. <TMPL_LOOP NAME='NAME'> and <TMPL_LOOP NAME='NAME_REVERSED'>. So you don't need to detect anything

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
