How to contact 3D warehouse uploader?

I found a model in the 3D warehouse which I would like to use in a way which seems to be in a gray area with regards to the license and TOS. The FAQ seems to suggest I contact the user, and this was my first thought as well, but I can’t find a way to do so. Am I missing something simple? How would I do that?

Are you able to place a comment on the model?
