When I was using eBay Blackthorne Pro SMP was provided free and I really enjoyed the auto-emails for just about everything. I'm sure you are taking advantage of that.
Also, after I signed up with Auctiva, while I was still on eBlackthorne, my listings started having the Auctiva scroll bar and I had done nothing. So I took it that Auctiva did that automatically.
When you create your listings in Auctiva, the code will be provided for you. Create and enjoy and use SMP for your auto needs, i.e. emails and relistings.
Hope this helps,
