A simple arithmetic test, 1 + 3 = [___] seems to be sufficient in most cases, for example.
savannah.gnu.org has that kind of test. We still get a few spam registrants. I think the math has to be harder. Some open-ended typography question ("Who designed Zapf Chancery?") would probably be spam-proof. karl _______________________________________________ Openfontlibrary mailing list Openfontlibrary@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/openfontlibrary
