There's a lot of ways you can help develop ModulOS. Programming, making specifications, helping with documentation and even sending ideias.
To do so, you can join SourceForge and be in charge of some task.
Other way, if you don't want to join SourceForge, is to choose a task and warn me about that. So I can mark the task as been executed. You can reach me at luizshigunov@users.sourceforge.net.
