If it's not really about tuning or wiring. Then it belongs in here.
Promotion popups come up in every window/browsing session regardless of dismissing the popup. Is it possible to have some sort of condition linked to a user profile so the promotion popup will no keep appearing once you have dismissed it?
Did we get anywhere with embedded images?
It isn't meant to pop up after it's dismissed but unfortunately it doesn't work that well.
I've updated it not to show on pages containing /Dashboard and /Forum. So it shouldn't pop up when you are looking at a course or the forum.
Hope this helps
