To save problems with showing questions, jsut remove it from ebay and sell it to me instead. [-o<
There must be an option somewhere to click to display the questions asked, when you receive a question you will get it in 'My Ebay' as a message and it will automatically be emailed to you aswell. If you reply to the email, then you will not be able to 'add' the question, if you have a look for it in 'My ebay' under the 'Messages' section, you will hopefully find an option.
Or, as I said, just sell it to me - do you have a 'buy it now' price in mind?
