If anyone was starting to write a guide for multi-column display for me after I so desperately asked, you're off the hook! It makes me sad that I had to switch to the Search Engine Which Must Not Be Named to do it, but at least I'm all hip and modern now. Rockin' five columns, and I may even add one more!
It seems like the kind of thing that would have information splattered all over the place, but was quite hard to find. Lots of "Here's what multi-column looks like, with hashtags and all, ain't it cool?" and not a word about how to make it happen. At least I got a chance to complain, which is always of great value.
