As you guys know, NGUI 2 is a free package. It's available for download free of charge, and can be used in any project, falling under the same restrictions as Unity Free. This also means that since it's free, Tasharen can't provide any dedicated support for it, but it doesn't mean that the community can't help each other out. The only issue was that there hasn't been a dedicated place for people to do so, and NGUI 2 questions were mingled with NGUI 3 questions in the support forum. Well, hopefully this forum will clear things up. If you're using NGUI 2, you are welcome to use this forum to post questions, and perhaps others can help you out.
