Melalvai, that sounds great. I think you'll find that some folks are VERY experienced with internet use, and others not at all, so maybe one of your first discussions could be about all the different sources they know and use, plus what you know about---and then you can leave the choice to them. I expect it's the bringing together a discussion group with you helping to provide the focus, structure and guidance that is what they want in taking such a class. It sounds like it'll be a ton of fun, really.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
