Dear Jens Lauritsen, EpiData Association Denmark

I am the co-ordinator of the Clinical Epidemiology Unit of my medical college in South India. We teach research methods to post graduate students and have been teaching epi-data for a few years, with a lot of positive reviews from students. We have now been trying out the epidata manager that you have introduced.We thought it would be a good idea to switch to teaching this to our residents rather than the earlier epidata. In this context, i need your advice 1. Is epidata manager ready for use by students-ie is it still in testing? 2. We seem to be running in to some trouble with using epidata manager-Sir, do you have a detailed user manual or online presentations that we can access to learn the use before teaching I look forward to your early reply I want to thank you again for this brilliant effort-many in developing countries with resource constraints are blessed by these efforts Thanking you regards
