Thank you very much for this! It didn't even cross my mind that something like this would be possible before I came across this. Everything didn't work out without glitch for me though - for one thing, people's names didn't appear on the reading page (just the icons), and the subject lines didn't work as links to the posts (which isn't a big deal, really.) Then I found this, a bit different source code for flexible squares, and it fixed those probs. But I wouldn't have come to look for it without this post, so thanks again!
