    • Well, Google's 'advertising optimization' has now become so distracting as to trick people into visiting other sites. So I have removed advertising until I can find a better solution. One option may be sponsorship, anyone interested?
  • Sponsorship!
    • We are very graitful to Neill, who supports BAMA in gratitute with his financial support
      • It's free to use, but every little amount helps keep it that way!
