In UnrealIRCd /sajoin is _not_ what Watchdog said. It allows you to force someone else to join a channel. The thing is, the user will be notified with a message like "someoper forced you to join #somechannel." svsjoin, which can only be used by services does not display that notice. The reason is, many IRC services programs have an autojoin feature. Basically a server-side autojoin list. They make use of SVSJOIN to accomplish that. It would be a pain if each time you connected and /ns identified that you'd get "nickserv forced you to join #thechannel."
