Dear Randy Tsen:

The EuroForth discussion group is about announces
and questions related to the annual EuroForth conference
(such as call for papers, submission deadline,
travel and arrival, etc.)

It is better to direct the questions like the one you asked
to the comp.lang.forth newsgroup.

To read/post-to comp.lang.forth at google:
http://groups.google.com/groups?group=comp.lang.forth
(NB: get a free mailbox [unless you already have got one]
e.g. at yahoo because you will reveal your From: address to spambots.)

Two more references:
About EuroForth:
http://dec.bournemouth.ac.uk/forth/euro/
About EuroForth'01:
http://dec.bournemouth.ac.uk/forth/euro/ef01.html

As to your question, I'll answer it in a private e-mail message.

Best regards, MLG
