It might help if I clarified what I'm looking for…
I have provided IR training for a number of years, primarily focusing on the Windows environment. I've done it on my own, and I do it now for my current employer. I tend to shy away from straight lecture…that does no one any good…and toward more functional training. To that end, I use scenarios to get points across and to let the attendees actually use the skills in question.
The purpose of my original question is two-fold. First, I have some very good scenarios that I've used for a while, and I'd like to "freshen" them a bit. Attendees to the training I give will need to be engaged, and ultimately walk away with a skill set. I want them to be able to actually use the tools and skills presented right away.
The second purpose is to post challenges online. Yes, I know that there are others out there, but many of them haven't been updated in a while. These things are engaging b/c they're new and varied. I've got some systems where I can post any data (volatile data captures, screen captures, etc.) to a site and allow others to try their hand at IR.
I hope that helps.
