Hi there
Is that list that you have mentioned public? Can you tell me more on the process of creating a listing on the eBay? I need to be sure that we are on the same page. Also, you want to get warned during the creation of that list (auto detection), or you want to start that extension by the click of the button?
How would you like to get warned, by a sound, or a popup?
Anyways, feel free to hit me up, so we can talk more about this. I am very responsive. All the best
