There is now a working draft of the simplified manual, updated 16th March 2010, which takes the reader up to ACE model-fitting in both matrix and path format. Just checked all scripts in it and made some corrections. Script to do full univariate ACE with nicely formatted output, including comparisons with saturated model, and AE/CE now added.
I think it would be useful to have this Wiki under Documentation, but am unsure if I can put it there, or if I need authorisation. It would be useful to have some feedback from beginners who try it out.
