Ease and simplicity are the things on which askcow is obviously based on and it has crucial features only. This isn't a mail agent, you know, or a bug tracker - it is a project management groupware and this is askcow main purpose. It is the only reason why we don't implement features you would never need.
Our goal is to make askcow as easy as possible. We find the projects quite difficult to run and additional complications of the tools of management are the last thing we'd like to put to use. Every piece of askcow facility was repeatedly discussed. Most likely you won't see it at all because we threw it out or even rebuilt askcow in order to make it even simpler.

FEATURES THAT WILL BE IMPLEMENTED IN CLOSE FUTURE:
Though you already can attach files to certain tasks, download and share them with your collaborators, we intend to develop additional features in order to improve and speed up the file management.
