I agree with you, but on the flip side....one time I was selling something on ebay. In the meantime we had a medical emergency at home, and to top it off, my PC crashed and it was a few days before I could check my emails. The item had sold during this time and the buyer couldnt contact me and was very annoyed. So while some sellers dont have good communication, other times it could just be circumstantial, like what happened to me. I was lucky though, the buyer left positive feedback once i finally managed to get back to him and explain what had happened. And its true, often buyer questions get sent straight to email and are not on 'my messages' in Ebay, so even if you checked ebay on a different computer you wont be able to see certain messages.

HTH.
