I've been wanting to implement enrollment end dates for a while now (I currently remind myself to go in and set the enrollment role to a higher role than most users have when I want to turn enrollment off).  I was thinking that I'd provide the changes back to be released with the DNN Events module but I'm wondering a few things.

A couple of other people have already been looking for this feature, but is it something that more than 3 people would care about using?  http://dnnevents.codeplex.com/workitem/20340  Note: I only care to implement enrollment start and end dates, I don't use fee based enrollments.

If I wanted to submit the code back, what's the process?  Is it documented somewhere?  With Git you create a fork and a merge request.  I've done an anonymous svn checkout of the code so far, but I'm sure I wouldn't be able to commit changes.

Is a C# version planned at all?  I thought I had read a while back that it was a goal for the module teams to convert to bring them in line with the core, was I dreaming that?
