Comment # 3 on bug 1113638 from Sean Lewis

I agree there should be some sort of parameter around using the workflow; I'm
more in favor of 1 week versus 2 weeks as it takes time to Stage/QA the update,
then roll it into TW to get user feedback on it. If someone will create the
workflow in Bugzilla I'll be glad to write a wiki article and we can tweak the
suggestion on etiquette/delay time later. 

On the automation topic, agreed there are a number of sources. Distrowatch
provides RSS feeds, Arch Packages is also a good source to track.
