no, the user table can't be altered twice, so once u have done the installation, u will always get that message. I suppose I could add a select to select the fields ... but, i'm not

At any rate, the only reason that I can think that it's not working is that you don't have a valid email address for your administrator (so sendmail balks when trying to send it out) or ur sendmail just isn't functioning ... or, it's also possible that whatever SPAM setup u have is blocking it as the sending address and reply-to address are different ... funny enough, that server setup is to AVOID SPAM, but when sending out mailings using PHP, it's one of ur only options.
