Hello, Eitan. Please do not post HTML. Plain text works just fine in
all of these news groups. Please also do not post binary attachments in
p.general, as Christoph kindly mentioned to you on 23-Jan-2001. For your
benefit, please read "Where can I post my binary or text file?", which
is posted in the p.announce.frequently-asked-questions group.
Please immediately cancel your post with the HTML and image attachment
in this group. Post your question again *without* attachments. Post the
image (and not HTML) in the p.binaries.images group with "Geometry
Question" as the Subject line and a line of text in the body stating
that the image is in reference to a question asked in p.general.
Thank you, Eitan, for your cooperation.
