Hello!
My mail is quite offtopic and it's not including any kind of solution but I
have one question - why you building that kind of feature?
Hmm.. prolly to avoid multi-account but in the muds there are two different
type players - cheaters and no cheaters :) And if anyone wanna cheat
(multiplay, spying for example) he just creating a new account and he would
be very foul player, if he start using same email as his/her original
account have.
My MUD having account system and not any kind of change needed - if anyone
multi-accounting (even account without any character) and we catch him/her -
then all of his characters and accounts will be nuked.

Subject: Questions about FORK.
Date: Tue, 15 Aug 2006 12:35:56 -0400
Ok.. I'm working on an account system, and want to make sure that no two
accounts have the same email address. Don't want users having duplicate
accounts. The issue I'm having is that during account creation I'm scanning
all the existing user accounts to see if any have the same address. I'm
using fork() so that I don't have the entire mud come to a screeching halt
while it scans, but for some reason, although everything in the fork()
seems to be working fine, it doesn't set the d->connected correctly or
process the nanny function again at the end the way I'm wanting it to.
Ideas? Thansk!
