From PackRat Recipe Wiki

Developers (devs for short) are the people who work for Alamofire and run the PackRat game. They are the official voice of PackRat. Oftentimes they are patrolling the discussion board and reading.

Unfortunately, when the boards were changed, developers' posts were no longer highlighted to tell them apart from regular PackRat users. You can, however, note which posters are part of the Alamofire Facebook network.
