We talked about this in the June 2nd, 2012 meeting. The gist of it is this:

I'm concerned that people who find GNU MediaGoblin via ​http://docs.mediagoblin.org/ never find out that:

1. it's a Free Software project
2. that they can contribute to
3. and that we'd like them to join

There's some material that's at the bottom of About GNU MediaGoblin, but it's not obvious that it's there from the TOC.

We have no metrics for any of this, so we're going on hunches, but generally, the things you want people to know should be right there on the front page.

I was thinking we could add a Contributor's Guide which covered some of the things in the wiki which I would update before every release.

Chris was thinking that's too much work and we probably don't get enough out of it and maybe it's sufficient to add some text and links to the index page.

As I'm writing this ticket, I think it might be good to put in something in the footer on every page, too.

This issue is for figuring out what's sufficient and doing it.

We had a problem with two migrations not working nicely on sqlite, because the second one wanted to do an alter table and sqlite doesn't like to do that in a bigger transaction. Long story: Every migration should say "I'm done" and commit. This happened for the existing migrations.

So. In my opinion, the migration framework should run a rollback after each migration "just in case" to clean up any cruft left over from a (possibly broken) migration.

- migration_func(self.session)
+ try:
+   migration_func(self.session)
+ finally:
+   self.session.rollback()

I have NOT TESTED this patch. This is just to show the idea. I want some feedback on it, and possibly someone to test it.

this error happened with two different videos in two different formats (avi and webm)
