Sir,
I have keen interest in your project and very passionate about it . I have installed DHIS2 and I am currently running it , it works very well as your youtube channel(http://www.youtube.com/user/dhis2?feature=watch) helped a lot.
I am planning to work on PROJECT IDEA :Dialplan (PBX) generation for patient communication ,
but facing some difficulty, I’m not able to find DHIS2-Tracker API that you have mentioned in your idea page (http://dhis2.org/gsoc2013) under Objectives.
