BTW, is there any way to edit a posting for such typos?
I sure hope not. Fixing a typo by replying to your own comment, like you have done, I believe is the best answer.
If we could edit our own posts, I could imagine that someone could modify what they wrote, to make someone who replied to them look stupid.
Anyway, I really like the way Jon has it that we must preview our posts before we publish them. I do just that. That is, I reread what I wrote before I hit "publish".
