- * LOWERS its timestamp value of the channel to match that of the winning
- * side, and the modes of the users of the winning side are merged in with
- * the losing side.
- *
- * The winning side on the other hand will ignore all user modes from the
- * losing side, so only its own modes get applied. Life is simple for those
- * who succeed at internets. :-)
- *
- * 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
