Fast ring insiders

Who is in the Fast or slow rings and like the new builds any problems report it in the feedback hub

I'm liking the builds. On PC (14971), Paint 3D is terribly sluggish but it's and old PC so that's expected. On mobile (14977), I can't archive Outlook messages from notification center, camera crashes, and flashlight works for about 5 seconds before a reboot is required to make it work again. But overall, pleased
 
We already have threads for this purpose, even tailored to individual builds I believe.
