London Institute for Contemporary Christianity have a very useful review of 13 discipleship courses. There is a 1-page overview based on presentation, ease of use, and application to whole life discipleship, as well as a more detailed review of each course. It covers Emmaus, A Life Worth Living (the Alpha sequel) Purpose Driven Life and all sorts of others.
The review dates from 2005, so I don't know if it's just been posted, or whether I'm even later than I usually am.
Really useful to have this all together in one place. Ht to the Diocese of Bath and Wells website, which seems to be emerging from its long slumber and has a few interesting new things on it.
