Yang, Welcome to the list!
Don't worry if you don't have time to fix everything. I know how it is to be facing deadlines. Log jira cases for the bugs & missing features you see. If you don't have chance to fix them, maybe someone else will. Don't be afraid to post questions or observations to this list, or start discussions. Since we don't all work in the same location, this is our only medium to get to know each other better, and take the project in the direction that serves all of our needs.
