If you have Web Developers just create a mini Website that will contain the information and log from input forms.

Even more elaborate methods are possible, just depends on the resources you have available to you and the time frame.

You can create interactive training pages with programs like Adobe Captivate or Camtasia

You could also create your own from within Flash Professional if you have someone to do it.

That way it's not so dull and drab and users still have to sign that they've attended/seen/read the material.
