Hi, I'm just an Lilypond user, not an programmer. I really think Lilypond is a core app for GNU/Linux musicians and many apps has Lilypond export functions. To keep improving Lilypond and because some people are starting to work on some Tablature improvements, which makes me really excited, I thought, let's make a call. Maybe you are a Lilypond user with a little programming background and want to contribute to Lilypond or you need a special feature/ improvement in it. Then you can start learning to do the programming yourself. You can start as a Frog, some kind of 'Lilypond student programmer'. You start learning the basics, maybe fix some bugs (like Frogs eat flies) and add some features you want with the help of the Lilypond developers. More info about developing for Lilypond: http://lilypond.org/web/devel/participating/ You can see the Contributors' Guide for some detailed information about participating: http://lilypond.org/doc/v2.13/Documentation/devel/contrib-guide/index#index At this moment there are some guys beginning to work on more and better Tablature functionality for Lilypond. Which is great imo also to get better Tablature functionality in GUI apps like Mscore and Tuxguitar. So maybe it's a good moment to jump in, and I think they can use some man power! See for example these threads: http://www.nabble.com/guitar-tab-feature-request-td21995370.html Thanks in advance, \r (Just an happy Lily user/ guitarist)
