I am unable to access the marketplace in my organization account. I have a free account but work on a two member organization account. I am only able to access the marketplace when I go to 'my sites' (with the free account I have) and click on '+new website'.
When I do this on our shared organization account I do not see the link for the template marketplace.
No rush! But it would be nice to access directly from my org account instead of transferring templates from my free account every time.
