Yes please! I would love to do a short survey to (at the very least) inform, LL about what's important to my store and my experience on the marketplace. Ultimately I'd love to see the form go to buyers as well as sellers and make a thing of it, widening the information gathered can only be a boon, but understand if this isn't possible at this time.
Also having this issue. After several tries I eventually log in, but the pictures are broken for me and not displaying. Other websites are fine, but Dashboard and Marketplace are both playing hide and seek apparently. I tried both Firefox AND Google Chrome and both just Hate anything SecondLife related.
