Sorry for the noise. When we migrated over, there was some miscommunication about how to recreated teh subscription data. I wrote up a guide over on the FAQ thread under “How do I unsubscribe from only chef or chef-dev?”. The short version is to go into your user preferences and un-check the “send me an email for every new post” option and then go to the chef-dev category page and set it to “Watching” so you’ll be emailed only of new posts in that category. Sorry again for the trouble!
