Great blogging skills, Paddie
For reasons known only to God, I have been given no "tech savvy" to speak of when it comes to the adequate operation of computers. I've been using Mac since 1993, but blogging only since July 2005. I have no idea why the font and size suddenly morphed into the virtually illegible mess you see before you.
I'd fall down and worship anyone with good advice on how to fix this. You provide the incence.
