To request a status on an existing issue, please update your report directly via the Apple Bug Reporter requesting a status update and we will provide you with any available information.
I got curious about this, and I went back to bugreport.apple.com to look at one of my pending bug reports and I didn't see any way of explicitly asking for a
status update. I feel that I'm missing something obvious, because I expect the FAQ to be correct, but so far I haven't got the faintest. Any help?
