Hello Andrew,
Thank you for your question about changing your eBay ID. If you change your UserID at eBay within the same account, our system will detect the change and apply the new UserID automatically.
After you have changed your eBay UserID, just go to BidSlammer Preferences and follow the steps to "Refresh Your Authorization."
Please let us know if you have any other questions, or require other assistance. We are happy to help.
