I have a site where I will be adding the Perch Members app soon. As a result, I've been reading about what it can do and how it works. It's a very useful app and third party developers have extended it as well. There are still opportunities to do more with it though and I've included a link to a forum post that describes some of the functionality that could be added.
On the subject of third party add-on development, I've also included a link to a list of third party apps for Perch. There are some great apps available.
See you next time.
