Usage: http://www.science.uva.nl/cgi-bin/mail_form?args
The arguments are separated by ampersand (&)
characters and should not contain spaces or equal (=)
characters other than for assignments (see below).
Possible parameters are:
sendto=email_address
sendsubj=subject
gotourl=url
sendto and gotourl are essential.
Leaving either empty will result in mail not being sent.
If the sendsubj is left empty, a default is used.
Other fields will be left unmodified and will be listed in
the mailed message body.
