Font Sizes?

Having had some complaints that the page text was hard to read from a number of comments received - all reviewed before publishing - I had a play.  

The grey on black and confusing links had to go.  So what you see if what you get.  I tinkered with the html on the CSS to make the font a little larger and that seems much better than before, plus of course I have chosen a lighter theme in any case.
