How and where do you want bugs or documentation errors reported?

I'm going through all of the TCMS 3 documentation and stacks in detail right now and I am finding errors in documentation and possible errors in some stacks. I wasn't sure whether to document them here or in some other way.

For example, I'm now looking at the Date stack in the TCMS3 Content. I noticed when I drug it onto the page that the default code shows as:

{{ cms.data("myobject") | date("Y-m-d H:i:s" }}

So it's missing the closing )

This remains true no matter what settings I modify.
