There seem to be some discrepancies here.  I did understand you had to be a Power Seller in order to be a Top Rated Seller and this is what I read in the ebay Power Seller info and Top Rated Seller info from the site map.

That said, you are clearly a Top Rated Seller, which is far more likely to be what buyers are looking for.

The advantages listed are "priority customer support" - :^O -  good luck with that one.

However I do enjoy the Power Seller discussion board and have learned a great many techniques from lurking there.  You also get some very straightforward advice.

ebay phone support is notoriously inaccurate in dispensing advice.  I suggest you check you are actually logged in to see if the Power Seller board icon appears.

If not, we will have to wait until due recognition by ebay before you join the throng.
