You mean there was a time when you knew nothing about ADSL?
yep indeedy.. back in about 2003. Long story but I had to take a 'crash course' on adsl and how it worked.. when there wasnt hardly anything anywhere about it on the internet, and as 'a swap' for me doing something with BT SFI, I asked a lot of questions.
Rizla was about one of the others... and unbeknown to me he at the same time was also trying to produce something and was actually drawing something up too.
I only saw what he did last year.. and I said to him why the hell didnt you publish it, and he said I'd beaten him to it.
Rizla must also get due credit because he's the person that did the one for adslguide (now ThinkBroadband).
