Thanks for that. :) Definitely wasn't expecting it. I may have wandered in with the wrong idea. I found this site linked from someone's blog, so I thought it was a plain old blog too, not a discussion community.

Sorry - my comment didn't add much to the discussion at all! But thanks for being helpful, everyone. After checking out your links, AngryParsley, this place is a bit too clever for me! Fascinating stuff, but I probably can't contribute. But I've recommended it to my more clever friends irl, who'll probably join in your sequences at some point.

Sorry again, guys! As you were. :)
