  34 <PRE>     Fixed with respect to guest nicks.  I'll work on the SQLINE stuff later.

  40 &gt;<i>The protection of guest nicknames and qline protection within SQLINES and
  41 </I>&gt;<i>IRCD.CONF QLines can be circumvented via the use of the '/ns link' command:
  42 </I>&gt;<i>
  43 </I>&gt;<i>nickserv/main: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> identified for nick Nick
  44 </I>&gt;<i>nickserv/link: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> linked nick oper to Nick
  45 </I>&gt;<i>nickserv/link: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> linked nick ircop to Nick
  46 </I>&gt;<i>nickserv/link: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> linked nick admin to Nick
  47 </I>&gt;<i>nickserv/link: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> linked nick Guest0 to Nick
  48 </I>&gt;<i>nickserv/link: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> linked nick Guest1 to Nick
  49 </I>&gt;<i>nickserv/link: nick!<A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices-coding">user at host</A> linked nick Guest2 to Nick
  50 </I>&gt;<i>
  51 </I>&gt;<i>... etc
  52 </I>&gt;<i>
  53 </I>&gt;<i>I imagine protecting guest nicks will be a trivial matter of adding the
  54 </I>&gt;<i>same check as used in '/ns register' to the '/ns link' command. Protecting
  55 </I>&gt;<i>against standard QLines would like;y prove more complex. I am happy to
  56 </I>&gt;<i>move/add all QLines to SQLines if there is a way for services to support
  57 </I>&gt;<i>protection from registration when used in this manner.
  58 </I>&gt;<i>
  59 </I>&gt;<i>Although the QLines will probably still protect against these registered
  60 </I>&gt;<i>names being actually used, they will allow the primary nick to receive
  61 </I>&gt;<i>memos to these banned nicknames and I guess there is the potential for
  62 </I>&gt;<i>further problems.
  63 </I>&gt;<i>
