mass join part if on UNREALIRCD servers .. you have server mode +j X;Y .it is designed to protect against join-part floods (revolving door floods). The mode takes a parameter of the form X:Y where X is the number of joins and Y is the number of seconds. If a user exceeds this limit, he/she will be prevented from joining the channel. to set it .. the command is /mode #channelname +j X:Y :)
note... This mode works on a per-user basis not global like mode +f :)
just food for thought to save scriptinh
