What, if anything, do you do with discussions with no response?

I have a few post without any responses. I don't know what to do with them either. I don't think you can do anything with them anyways.

i have the same problem. they really should add a delete button. i actually get tired of seeing them

As for what you can do, or are capable of doing as I have learned is stated in my above response. I am not sure if it helps or hinders but that's how it seems to be working so far. I had a discussion that only had three responses so I went to the discussion and rated each one as well as marked the best response. I later figured out that doing that resolved the discussion, so I no longer had an unresolved discussion. Hope this is helpful!
