+Thanks for offering to help with QA testing. We recently finished the Moodle 2.8 QA cycle, so our next QA cycle won't be for a while, however you are welcome to try things out on our Moodle QA Testing site http://qa.moodle.net/ and post in the Testing and QA forum http://moodle.org/mod/forum/view.php?id=56 about any issues you come across, or any questions you have. If you come across any bugs (obvious problems), please report them in the Moodle tracker.

+
+Thanks for helping with QA testing. Your help would be appreciated even more if you could just add a comment when passing a test, such as feedback about the feature e.g. “Teachers are going to love this” or even simply "This test passes - yippee!" to confirm that the test wasn't accidentally passed without being run.
+
+Thanks for helping with QA testing. It has been observed that you assigned this issue to yourself for testing, but no action has been taken on this.  It will be helpful if you can either test this or un-assign yourself, so someone else can take it.
