Hi again!

This is yet another question that you may be able to help :-).  One of
the guys who will make presentations at our SFD (Campinas, Brazil) asked
if he could receive a certificate for attending and presenting at the
event.  I was wondering if SFD has an official template for such
certificates.  If not, I will probably try to come up with something,
but I do accept suggestions, of course.

Thanks!
