Well I have been in the QA group for a few weeks now. Mostly I have been running the standard test procedures on the nightly drops for F28 and running the canned regression tests on new versions of the Kernel. I've occasionally tested updates when I could recognize what a particular update was and had an idea how to test it. I've also done some tagging of packages.
I think I need a mentor; so I think I'll send a note to the list and see if anyone is willing.
