Maybe I'm stupid, maybe I'm TL;DR, but, where is the short version of configuring CB like in the demo? Can't find it.
The demo site has little to no changes to default configuration. The home page is a menu item to CB Activity recent activity page and a few system actions are enabled that aren't default enabled within CB Auto Actions. There's a few other things like CB Conditional configured to show/hide some fields, CB Core Fields Ajax enabled for a few fields for ajax editing, and CB Privacy enabled for some fields to have privacy controls. For the most part everything is more less installed, enabled, and left as default. You can review the backend of our demo site by clicking Administrator under Login As.
I have a client with a paid subscription on here...if an admin needs to see it before helping me, I'll PM his details.
You will need to post from that account in the support forums. Sorry, but we do not provide product support for accounts without an active subscription.
