I was looking for some information today and tripped across this great site. The IDS people have done it again and have created a primer to help you get used to ILLiad 8.

I also have a link to the ILLiad 8 documentation on the blogroll if you have a burning question on how to do something and cannot figure it out. I have been using this a lot, it has saved me many times from getting frustrated.
