Spent a little time sprucing up the design. Chose an excellent layout from the themes tab in design. Changed the banner image for a picture taken in Yosemite Valley in 2007.
It seems quite straightforward to use. The options seem to be limited – or they may be limited to free blog owners. I found a three column design I like but there is no indication that I can upload it and use it to replace my existing theme. I have much more exploration to do before I will know the extent of customization available.
Help files here I come – but not until I’ve slept. Goodnight.
