Dear Jutta,
If yuou are willing and able to
pay for your own license, contact
leslie at gcg.com .
Otherwise, they may able to put you in
touch with a site in England that you can
use, for an extra licensing fee. We are an American
University who sometimes let private companies
use GCG on our computer, but they have to pay
an extra licensing fee to GCG. perhaps you
can work put a similar arrangement in England.
