Now you can follow your favorite member stores. To follow a store, use the button on the upper right corner of their store page. This feature will be available for stores who have a MorphMarket membership.
Having followed some stores, you can access the full list of stores you're following from the menu on the Followed Store page. From the Followed Stores page use the button in the upper right corner to access a feed of the newest stuff they have posted.
Coming soon -- a long time and highly requested complimentary feature: Ignore Store. This will exclude stores from any search results.
