That's interesting as I've not heard a great deal of information about Microsoft Learning Gateway and how it compares to Moodle. You just get the marketing hype and that's it from Microsoft.
Off track there for a moment. Until the IMS CP part of release 1.6 is sorted out, I'd suggest to anyone, as you did, to use the Object module from Moodles site. I installed it and miracle of miracles I can now use the NLN Materials with great ease.
Many thanks to you and everyone else who's helped out with replies in the past. The SCORM module also works, but it's not as simple as the Object one and doesn't really give me things in the form I'd prefer them.
