-<PRE>Odd scenario, and I am not sure whether services should/could support it,
-but since it seems to be the cause of a particular chain of log messages,
-it could well be something for the FAQ if it is not something that
-should/could be supported.
-
-A user logs on to IRC, identifies to NickServ then joins a channel that he
-has auto-op rights on. He then immediately changes nickname to another
-nickname (registered or not). Services logs the fact that a mode change was
-requested for a nonexistant user. The nicknames in the example are not
-linked.
-
-><i>From logs:
-</I>
-[channel]
-[14:38] Damon (<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">damon at xxxx</A>) joined #channel.
-[14:38] Nick change: Damon -> Memphis
-
-[Services.log]
-[Mar 02 14:38:59 2002] nickserv/main: Damon!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">damon at xxxx</A> identified for nick
-Damon
-[Mar 02 14:38:59 2002] channel: MODE #channel +o for nonexistent user Damon
-[Mar 02 14:39:13 2002] nickserv/main: Memphis!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">damon at xxxx</A> identified for
-nick Memphis
-
-I have not managed to be quick enough to reproduce this 100% hence my lack
-of knowledge on whether this affects linked nicknames, but in my defence it
-is kinda late here and the timing is somewhat critical :). I suspect that
-it may apply to linked nicknames as well but assuming that services logs an
-error returned by the attempt to set a mode, I imagine the linked nick
-would trigger another test which may make mitigate the problem from a
-user's perspective.
-
-I guess it would quite complex for services to track the user and supress
-the error as well as leading to potential circular lockup, so maybe just
-one for the FAQ.
