    Re: suggestion for a satisfactory celnav narrative
    From: Robert Gainer

    I think the project is worth doing, but I don�t have the skill set required
    to help much with the knowledge base. I will however contribute server space
    and setup help if that will get this started. I am already contributing
    server space to Dan Hogan and his Nav-L web page.
    Maybe this can all be combined into one project on the Nav-L page. Jim
    Thompson has what I think is an excellent website in the form of study notes
    that he has posted, maybe that can be the start of the text, or maybe that
    can be the text and it may stay at his site and links can be established to
    his work at other sites such as the Nav-L page. All of that is of course up
    to Jim Thompson and Dan Hogan.
    I am open to suggestions as to how this should be pursued, I am willing to
    spend some time, and money to accomplish what is decided by the consensus of
    the group.
