137 * 2) The channel is desynced. That can STILL happen with TS
139 * Now, the old code roger wrote, would allow the KICK to
140 * go through. Thats quite legit, but lets weird things like
141 * KICKS by users who appear not to be chanopped happen,
142 * or even neater, they appear not to be on the channel.
143 * This fits every definition of a desync, doesn't it? ;-)
144 * So I will allow the KICK, otherwise, things are MUCH worse.
145 * But I will warn it as a possible desync.

194 * - In the case of a server kicking a user (i.e. CLEARCHAN),
195 * the kick should show up as coming from the server which did
197 * - Personally, flame and I believe that server kicks shouldn't
198 * be sent anyways. Just waiting for some oper to abuse it...
