403 error in Webmaster Tools

Hi there!

So, the only Muut indexes that will be generated are for threads with content—I see the post that the above index link for has no comments, so it is actually the expected functionality that it not return an index. You can see at http://chickenreview.com/i/chicken-talk/www.chickenreview.com/1294:comments (which is the index for the comments on http://chickenreview.com/types-of-chickens/) that the index is being generated. So, the 403 is currently the expected response on the comments indexes for posts without comments.

It is on our roadmap to revisit the non-existing indexes and investigate if there is a better option we want to take, but for now know that when you have commenting content, it is having an index properly generated and available.

Let me know if you have any other questions!
