Support Form: 主要的官方支援，The “official” support venue. Report “something is down” here. Feature requests likely to get a canned “we’ll consider it, but no promises” response.
Google Groups: 主要是成員討論，Active involvement by the core team with the usual caveats about turnaround time in group-oriented mail systems. Best place for highly technical discussions about app internals and “weird” issues.
StackOverflow: 疑難雜症，Slow/unpredictable response times but best place for backup reference material. If you’ve read a Q&A on StackOverflow, you know the type of question that’s best to post there, too.
該用兩個 reference 就用，不要想說用他們共通的父節點來存取，這樣沒有比較省。If you need to reference an object from two different places, take two refs to it.
