I'm stuck at 3/4 (and willing to go over 4) but I can't think of a good way to utilize my skillset rather than just taking the good first-timer issues away from new devs.

My specific thoughts for me, but the question in the title can hold for any QA:

My day-to-day is in Jasmine, so I might be able to find a JS project and clean up unit tests, but most of my work is in feature verification. It's not really realistic to jump in out of nowhere and start writing end-to-end tests when you don't actually know what the requirements are or what a good regression suite to tie into CI would need to look like.

So what should a QA do to be most helpful during Hacktoberfest?
