Is it possible to say...use only the "Topics" section of postnuke and incorporate that section into a regular html website? I don't want my entire website being pure postnuke, but the topics section is convenient as my website relies on updated information on a daily basis. Maybe it is somehow possible to RSS feed the topics to a regular page? so for exmaple on my webpage like this: http://www.sportscardomain.com/Acura.htm I want to have incorporated postnuke topics.... is this doable?
You could have postnuke installed in a directory behind your primary then use its blocks to navigate the content. While that doesnt make much sense it does answer your question. I would rather see you just make a topics and db outside of postnuke. Or incorporate your html inside postnuke. I have alot of experience with postnuke if you need help.
I am now thinking it will probably be much easier to setup a blog and than feed that to my site using CaRP - apparently it can parse a feed and output it as html so I shouldn't have a problem with search engines.
