I settled on one over-arching design for the various sections of Jephnol, so I had to make some changes on the back-end of the site. There's one designated banner now to solidify the Jephnol brand. Also, styles will be universal on the site, which allowed me to designate a common style sheet rather than using one for each section.
The blogs aren't new Movable Type installs, but instead they each share the common MySQL database with Jephnol proper. (I don't expect traffic).
The image paths were a bit messy in the Photo Blog and Byron Blog, so I created new image folders for each root file, and cleaned up all the corresponding code in previous postings. This won't make much of a difference to readers, but it makes administering the blog easier for me.
Anyway, that's what I've been doing.
