My twitter handle is @grymoire and I will gladly try to answer questions.
Most of these tutorials were written from 1989 - to 1995 for The Sun Observer. But I have been keeping them up to date the best I can.
Over the years I strive to make the pages compliant with the validation engines.
I'd give you my e-mail address, but frankly I think spammers should rot in hell. Therefore I'll give you my e-mail address in longhand form.
