[Glastonbury] Javascript

[glastonbury@mailman.lug.org.uk]

A few things here i didn't know. had a feeling that PHP was more useful in a 
sense, so looking forward to learning more about it.

Am interested in site design for people with disabilities. Know that Jacob 
Nielsson is into this in depth, and that it is a contemporary issue to be 
considered in design these days. (LIFT, etc)

anyway, cheers;
