Don't feel bad about replying to old posts. It's encouraged here, actually—though I don't know if it will be forever (I guess it depends on how we like it when the forums are larger; I tend to think it'll still be encouraged then, though, since we don't want too many ridiculous restrictions).
Honestly, though, I don't remember ever even seeing this post (or the other one by the same author). That strikes me as odd, somehow.
