[R-390] The Y2K Maintenance Addendum (was: Christmas Wish List)

[Barry Hauser]

Hi Roy & gang ...

I second the nomination!

Not sure though about what's fit for the addendum vs. incorporated within, 
but it's a practical approach to alow things to move forward and avoid too 
many versions.

The Hollow State Newsletter web site has plenty of room and unlimited 
bandwidth.  I offer that as a collection point for works in progress and 
completed modules.  There they can be looked over and recommendations for 
additional material and edits could be communicated to Roy and/or others 
developing contributions.  When the dust settles on a piece -- i.e. no more 
comments coming in, it could be "finalized".

To avoid confusion, duplication of effort, etc., changes should be routed 
through the original author/compiler.

This is not to displace Al Tirevold's site which should remain central. 
However, I suspect Al has been very busy and travels quite a bit.  So, we 
can do this for the time being -- and the HSN website is also appropriate as 
an expansion site long term.

Make sense?

Barry
