We normally add the following Help and Training site to IIS as a value-add on our Lync engagements but recently there was a requirement for a customer to have a look at the material before we were engaged.

As such I published the site so they could have a look externally without having to bother installing any fiddly bits themselves.

Feel free to take a look.

Good luck
