While what chanroles are trying to accomplish is a good idea, it is apparently unclear this is the proper way to do it. Until we figure out the exact way we wish to do this, it should be reverted for now.

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