Is there a way to show comments only on vehicles I added? Often I am interested to see if anyone has identified an "unknown", or commented on a vehicle (or movie) I uploaded in the past. So if there were a way to filter the results from the "See all comments" link that'd be very cool!

I think it would be a helpful feature if possible

You can easily see all comments on a movie: there is a link on the movie page under the gallery, just before movie comments.
So you can already check the comments made on movies you added recently.

Oh yeah! Thanks, I'm a n00b and forgot about that feature
