I didn't cross-post, I posted to uk.d-i-y. I don't cross-post, and to my recollection have never done so. I was a newbie when there was no such definition as a newbie, 'cos everyone was a newbie. Cross-posting was frowned upon right from the start.
Bottom or top posting isn't a standard, it's a guideline. There are certainly plenty guidelines which suggest bottom-posting, but I think they're crap.
