Well, if the shoe fits... especially if it matches the skirt!
Kidding aside, my main concern was not to lose the original post. I often just update my original code. I do that because I don't consider it to be a new version, just a work in progress; but Ken's situation got me thinking about organizing multiple versions. So now, if I had a finished work, I would preserve it, and post the newer version in a new code box, inside the original post. That's because I favor keeping the code first, and discussion about the code in the subsequent posts. I also don't believe too many people searching for code want to read complete threads. If I did believe that, I would post the new version in the next available reply space, but I don't, so I won't. Anyway, it's really not a big deal one way or the other. Just a matter of personal preference.
