I'm not frequently visiting your community and wanted to give some feedback, which I found troublesome.
When I chosed TeamCity => FeedBack => Submit Feedback, I came to this page.
The page is a jungle of word that tells my how to not submit feedback to you.
And after to much effort I found your community but could not post, and no information why.
I finally found that I had to be logged in.
So if you want to have more feedback, this is where to start. Make it easier to submit feedback to your product.
If you don't want to have feedback, leave it like it is.
