Some of our clientel have requested an ability to print a sequence of topics from the wiki so I am currently adjusting this module further to incorporate firstly a print topic button at the bottom of the page. Integrateing ater that a new tag __viewtoc__ & __endviewtoc__.

This would allow the user to create a different toc on each topic but this would allow the user to view a heriarchical reprisentation of a topic, whilst still maintaining the integrity and the advantages of using a wiki

if anyone would like the source I'll post update once I've completed, which will before the end of the day...

Okay after much battering and some hard work I have got a solution that works for what we need internally.
Due to some demand I have adjusted it further internally to export to a "word" file the quotes are used as thsi is essentially a html file that I have assigned the mime type as application/msword.
Okay the source for this modification will be available at http://ewds.strath.ac.uk/development.aspx 
I would suggest that the dll is simply copied in place of the current wiki dll and there are also a number of other files which need to be copied into place. I appologise but I am currently still getting used to the dnn packaging and am pretty sure I haven't yet got the hang of it.
As per Chris' Request I'll post the source alterations ups to gemini or alike for any possible inclusion in the source etc...
