I see the Knowledge Management component as the ability to store any kind of document (word, pdf, excel etc...)to index and search (natural language as well as keyword, boolean, wild cards etc...), FAQ's-ranked and sorted, expert lists.
Irene: Yes I do know of 2 that fit, and I now of one very capable KM platform that can also function as a LMS "lite" If you would like to start a conversation around this email me at scase20@juno.com. I can share my research and ideas and possibly help you determine the exact features and function that would meet your need. I also have a friend who has implemented a KM platform an talking with her might help you determine what is needed.. steve
What you seem to be asking is not about a LMS, but a robust FAQ and/or Document Management product. Given that your asking more about document managment, I would suggest looking at: http://www.fixitks.co.uk/fproducts.asp
They have a very robust system, with a quality security system.
