Hello there! This is my first post in the forums to do forgive me if I'm a complete scrublord :3

I'm making a little quest/companion mod with its own radio station, and since this is my first time using the GECK to actually do interesting things, I'm not entirely sure with what I'm doing.

I'd like to add a notification window to my mod that opens once the game is loaded up, much like the ones that open when new DLC is installed, to alert the player that a new radio station is available as it sort of introduces the quest and the companions, but I don't really know how and I can't seem to find any guides anywhere that can help me out

Any help would be much appreciated, and if you need any other information I will do my best to give it ya
