Sidebar elements are temporarily missing because they were deleted when I tried a couple of new third party templates on for size. They'll all be back up soon, along with a new look. My mistake was I copied the blog's html, instead of downloading it, because I could have easily reverted had I done it right.
At any rate, the third party template seems to be working fine on another test site, giving me 3-columns in blogger. A couple of minor glitches - having to reload all the links and gadgets and page elements being one (but AT LEAST THEY CAN BE ADDED!) - the other is that in Safari, the edit pencil is missing on the main page, so I have to go in through the dashboard to edit.
Here's where I got 'em -
the guy is good - lots to choose from INCLUDING a set of enhanced perfect matches to blogger templates.
Eh - I went back to two columns for now. Quickedit is a necessity.
