Hello kev600,
Just unlike Fred wrote, layout wise, I like it, although the selected text colors make it hard to read (at least for me).
Content wise, it is indeed well done, but I didn't find anywhere the sources of the documents and of the info.
Citing your sources would greatly increase the value of the site, giving a more professional touch, and simultaneously would enhance the added value of your own writings.
Thereby, giving tribute to the authors will encourage them to help you enrich the site.
Anyway, good luck with the site
Regards,
Luc
