Sorry to sound stupid. Have played Skyrim since it came out. But, hey, I am 70 and have never dl'ed a mod. I would love to have new content, places, but don't want to get into a

situation where I am having difficulty downloading or having my game crash. Suggestions?

Start by taking some time to watch the videos on https://www.youtube.com/playlist?list=PLE7DlYarj-DdhDG41roBVJfNCqvO5MmKP. This is probably the most comprehensive beginner's guide to using mods in Skyrim there is.

Hey, thanx, Gator Country. Did not know about this.
