Chiff and Fipple Forums

I bought a copy of the Irish Glance Card but I'm finding it very difficult to find an online source that will explain it. The only one I've come across so far is a number of videos by Cumann na Gaeilge i mBoston · and while they are very good I'm seeking a written description of how to us it. I feel this would be of great help to me.

Has anyone her experience of using it?

As always many thanks for reply's and suggestions
