Okay folks! With the help of Miss Becky Jeffers we figured out how to add an app!
Go to Create
Under the box where you write your discussion, there are 3 words: @Mention ! App Attach
Click on ! App
Then click on Find !App in the Jive Market
From there, pick the one you want! Becky and I chose the Props one
Hope this helps! Davinci Wallace make sure you look at this!
