Please note that our PULL process for reviewing code for integration has changed.
The workflow for pulls has now been integrated into the main workflow for MDL issues, and is no longer a separate PULL project in the tracker.
The main benefits of this are keeping it simpler for users, and reducing the problems of discussions being spread across multiple places. Viewing the History tab will give you a complete history of the issue, including failed PULLs.
For more details about the new workflow see http://docs.moodle.org/en/Development:Process in Moodle Docs. It's still being tweaked/improved too so please let me know of you find any problems.
