I want to help with this call for testing and I've already made a start with my Nexus7, but I'm not sure if I'm doing it right! I'm not very technical , not really familiar with GitHub, but I'm a big fan of UBPorts, ubuntu touch and ubuntu generally and want to make some sort of contribution.
So I've set the Nexus 7 to the rc channel and tested a few things in the list on the OTA-8 tracker and posted the results as a comment directly at the bottom of the issue page on github. Is that the right place to post the feedback?
Also, are you asking for testing of the QA issues regardless of device type? What I mean is should I just go down the list and try each issue in turn? Would it be useful to do this also with my M10 and E4.5?
