There is a long time since Emacs.SE went out of beta. When will there be header graphics for the site and a logo like the other SE sites?
It used to be that sites graduated from beta at the flip of a switch, but this is now a more gradual process. Emacs.SE now has no “beta” in its name, has had moderator elections, has community ads, but has not yet reached the last two steps: a distinct design and increased reputation requirements for privileges.
Computer Science graduated in September 2015 and its designed launched on February 1st. Software Recommendations also graduated in September 2015 and design work is starting now. There was a pretty big wave of graduations around that time as the rules changed. We graduated two months later so I expect we'll get a design in a few months or so, once the backlog of the September 2015 wave has been processed.
