I heard Peter Ford mention Dave Severn in a talk he gave somewhere recently. Peter was excited about having Dave act as an online mentor to some drop-out/thrown out teenagers he was dealing with. They created photos, Peter uploaded them, and Dave took a look and posted comments. Peter was thrilled at the interest and enthusiasm shown by these "difficult" kids.
So I was interested to see an example of Dave Severn's work on this post of Peter's. And here's a link to Dave Severn's own website.
