Can't post to action directory

I’ve made a few nice actions with the Trello API and was planning to post them to the Action Directory. I must be missing something, but I can’t see how to add an Action to the Directory.

Steps for sharing to the directory are in the action directory docs.

Short story: It’s at the bottom of the edit screen for an action.

Thanks. Typically I found it, on the Mac version, moments after posting!
