Here you can submit your bugs and feature requests. Before you do so, you can check if somebody else has already submitted the bug or feature. You can also check the wiki pages [Setting up your GTD mind map] and [Synchronise your GTD mind map with todo.txt] that describe how GTD Sync should behave. If you observe behaviour that deviates from these descriptions, you should submit a bug. Otherwise you should submit a feature if current GTD Sync behaviour is bothering you. If you are in doubt you can also start a topic on [discussion:general]
You might want to submit a bug because GTD Sync has upset you and/or because you cannot understand why GTD Sync is behaving the way it does. I would like to urge you to express yourself in a respectful manner when describing the bug or when reacting to the response. Possibly your perspective is different from the intended GTD Sync perspective and I recommend that you read [The GTD Sync perspective] before you submit a bug or feature.
