It has been great to see all the Finds people are collecting and including in forum posts. Over the last week I've fixed a few teething problems and also added support for several more stores. The store count is currently at 36, but we'll be adding more over time.
Note that you can see the stores supported on the right hand side of the Finds help page.
We've also added the ability to specify the order of finds that you attach to your forum posts. As you compose your post you will notice little arrows above the card of each item you add (to the left and right of the "Remove" link). Hitting these arrows will move the item in that direction.
For example, in the attached screenshot, clicking the arrow I've highlighted with a yellow circle will move black jacket in the middle one position to the left. It will swap places with the orange jacket and end up with the order of the items I attached below.
