Thank you mglae - I can now see it.
I just thought it would be nice for antiques such as myself to have it in a book form. I'm used to reading sequentially not jumping around so I had a quick look and found
Is the Print/Export feature enabled somewhere?
The post doesn't make sense (replying to the correct thread?). The LE wiki has an export to PDF option. The forum; nothing in the forum sw as printing a forum thread isn't something most users would want/need to do. You can still print the contents of screen in a browser though.
It made sense to me 
Essentially it was the fact that there are loads of options throughout the system and I have tried to read wikis (not just Kodi's) with a marked lack of success.
Unless I mistook something the pdf export is one "page" at a time - so I'd have to follow the links around and manage (hopefully) to collate in meaningful order. I would not rate my chances of success particularly high.
^ You can download the LE wiki there in zip format. Then you have to learn to like reading markdown format, but it might beat trying to export online sources to PDF (which they are inevitably not designed for).
