[News.eclipse.foundation] process for submitting a contribution to a pro

[Dave Kelsey <dkel50@xxxxxxxxxxxxxxxxx>]

I have been looking to see if there is a standard eclipse project process for contributing to a project but I can't seem to find it.
I see some projects define themselves a process for submission but I wondered if their wasn't one for all projects.
For example, if someone wanted to contribute new code (which has been written to the eclipse coding standards) to a project, how should
they go about submitting this to the project ? How long should they expect to wait to here if their contribution has been accepted or
rejected, and what can be done if they feel the rejection is unfair. If accepted, I would assume the contributer becomes a "developer"
so that they could be responsible for fixes and further enhancements ?

Any information on this would be great
