I was having trouble figuring out how to get to the Red Rig Showcase Form from the Link provided on the right in the instructions. I have also noticed several other people posting and saying they could not get to the form as well so I thought this might help some other newbie such as myself. When you click the link and go to the Jive App Store it seems you have to install the "Forms" app (on 2nd page of apps for me). Once I installed it and re-clicked the link the form showed up!! Hopefully this helps someone and if nothing else it will give everyone else a opportunity to point and laugh at my simpleness behind my back
Off to post my machine for all to see!!
