I can just see someone getting 100,000 emails from a one line bug, and of course someone will keep using the broken version until who only knowns when. Hmmm.. A timeout feature in send() might not be a bad idea ("don't send e-mails after..."). OTOH I think I might have posted a broken version. Could someone test it out and such?/* * Hacked this together, though y'all might like it. <g>* */...encapsulate an e-mail logging system.Excellent! IMNSHO This ought to be in both Phobos and Ares.
