Folks,
As a first step of the implementation of the WineConf decisions, the patch tracker now supports Signed-off-by. You can see the list of people who have signed off on a patch by hovering over the signed-off checkmark in the tracker.
In general, people who are listed in the MAINTAINERS file should sign off on other people's patches that touch their area. I'll be working next on implementing a more formal mechanism for assigning reviewing responsibility.
To add your sign-off to a patch that you have approved, you need to send a reply to wine-patches with your Signed-off-by header. If you find this inconvenient, I'm open to adding other mechanisms; suggestions are welcome.
Finally, starting next week I'm going to require patch authors to include a proper Signed-off-by header on all patches.
