Well, one of my readers couldn't read the text on the black layout. :(
After cruising through all the options, only one other caught my fancy, but it cut my sidebar photos in half - that's no good - so I'm back to the blue.
Still, it's a nice layout and it's worked for me for a year and change. If it ain't broke, don't fix it, eh?
Here you are< Swampy! Happy reading!
