BTW, it’s not really a secret, it doesn’t involve special codes or anything, and I hate to be mysterious (and I would trust shlishi and pba not to abuse it) but if everyone would know how to do it, as r-b said, the cr would go berserk.
And, pba, I thought like you until r-b said it could be done (and then I found it).
Aren’t you Mod 80 anyway? 🙂
