I saw the sticky about the new site after I tried to navigate through the marketplace. I'm sure these are already known issues, but if not, here you go. 

1. Tried using merchant name to get to their page, since there was no button to press I thought it would automatically hit enter for me, nothing happened, hit enter on the keyboard and it pulled down the merchant list again. 

2. I went to the main market page and selected to search the merchant via that way. Got to their page, they had 3 or 4 pages of stuff. Each time I selected page 2, it would just refresh the first page, would not let me get past page 1.
