The idea of a forum is interesting. We sure have our Github for suggestions and issues, but most people don't use it or know how to use it. And it's also always good to hear what people want, whether from emails, polls or posts; albeit most of the time people won't know they want something until you show it to them. And that's mostly our place to think about new ways to make Notes better and improve it. Not degrading at all from the power of our users to tell us what they want, but it's imprtant to not be take every suggestion (even with majority) to be a final decision. We should everything under own ideas and values and choose the ones that fit the most with our vision.
I think Wix has some built-in forum capabilities, I should check out on that sometime.
