   F_REG   Registered access allowed flag
   F_SEL   This conference selected for message scan
   F_SYS   User has SysOp access in this conference

 Values
  F_EXP = 2  = 10b    = 2o  = 2h
  F_MW  = 10 = 10000b = 20o = 10h
  F_REG = 1  = 1b     = 1o  = 1h
  F_SEL = 4  = 100b   = 4o  = 4h
  F_SYS = 8  = 1000b  = 10o = 8h
