Perhaps it has something to do with stretching the time-space continuum? can someone explain this in words of five syllables or less? a. >_______________________________________________ >IIU mailing list >IIU@iiu.taint.org >http://iiu.taint.org/mailman/listinfo/iiu -- Antoin O Lachtnain ** antoin@eire.com ** http://www.eire.com ** +353-87-240-6691 _______________________________________________ IIU mailing list IIU@iiu.taint.org http://iiu.taint.org/mailman/listinfo/iiu
