We are at least a year away from T3 due to lack of circuit facilities. let's figure a way to stop at least some of the abuse; you can not stop the individual abuse, but does a spammer have any rights? --attila -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: latin1 Comment: No safety this side of the grave.
