- * NOTE: Unlike TS6 and dreamforge and other protocols which have SJOIN,
- * FJOIN does not contain the simple-modes such as +iklmnsp. Why not,
- * you ask? Well, quite simply because we don't need to. They'll be sent
- * after the FJOIN by FMODE, and FMODE is timestamped, so in the event
- * the losing side sends any modes for the channel which shouldnt win,
- * they wont as their timestamp will be too high :-)
