The format of the pages for GIS Stack Exchange has changed, and the link to Meta is no longer where it was on the top bar.
Did I miss an announcement?
A New Top Bar for Stack Exchange
The top bar of a Stack Exchange site has always been a bit of an odd place. It somehow combines user info, navigation, search, and a one-size-fits-all popup that includes hot network questions, a list of 100+ Stack Exchange sites, personal inbox messages, and other system notifications (lovingly referred to as The StackExchange™ MultiCollider SuperDropdown™).
It was, in retrospect, overdue for a face-lift which is why we’re excited to roll out a new top bar this week.
It would be nice if these kinds of changes showed up as a notification on the child sites though.
