Rafael,
Could you tell us about the dotTeach status nowadays?
I downloaded the 1.0 version and sample data from Surath page at WEG (http://www.weg.ee.usyd.edu.au/people/surath/) but dotTeach page here http://www.weg.ee.usyd.edu.au/projects/dotteach/ says current version is 1.5. Unfortunately link to 1.5 version download is broken.
This version is available in other location? Could i get the last code available?
