I have an idea, Lets create a web page outlining current multimedia projects. It does not have to be anything fancy and I think it may help not just the current mpeg project but other multimedia tools. If no one steps in , I will create such a web page -- hint I am looking for a volunteer 8) The list is fine to brain storm ideas . I just don't want others at a later time to miss the "brain storm" 8) Tnks, Amancio >From The Desk Of "Eric L.
