Bug reports and feature requests are kept on Sourceforge. The sample programs that come with NXT provide commented example code.

However, there is a space here for a general overview of the programmers' API provided by NXT, but currently there's only the Javadoc that comes with the NXT dowload. We will generally provide Javadoc from the latest CVS build which will not necessarily tally with the NXT version you downloaded, so don't rely on it.
