She would also put up her full family history, as edited by herself, and show her grievances against the fairy royals. She would be remarkably honest about her own shortcomings, this is one trait she shares with her cousin, Eileen, but she would be even more ruthless about others' failings!
The Witch would not invite comments to her page. It is for her to issue comments on others (though as a precaution and in anticipation of this the Queen and Eileen would block comments being received on their pages too as they could guess what the Witch would say. And as the Queen once remarked to Eileen, "if we wish to sit through a torrent of strong language, we will merely convene another Council meeting"!).
The Witch would also show examples of how brilliant her ancestors have been and advertise what she thinks makes a great witch. She would also show just how rotten fairies are and moan about who has had the better press over the centuries.
