If you have always wanted to start with GNUmed coding but did not know how here is another chance.
Build a feedback plugin.
Build a simple plugin which will be loaded when someone connects to the public database.
Give it a field to put in some text. Sound complicated but it is not. You can reuse the code from the error reporter built into GNUmed.
Once you have accomplished that very useful task a number of features come to mind.
Aks the user about their platform, language, missing features and whatnot.
Go for it. This is your chance to help out GNUmed by starting with a beginner job.
If you need help just let us know.
