ok.  We are making some noticeable progress
already, thanks to Diane, Stefan, Erik and Steve...

Thanks for starting up on this, Conor.

I think it would be great if we can document this
piece too.  For example details on how to create
the branch, how to apply patches to a branch and how
to do multiple merge backs.  If we point to a link that
discusses this in detail, that would be helpful too.
I will try to identify some such link also, meanwhile.

ok.  Do we have to take care while tagging, by
avoiding tagging of proposal tree, etc?

Do we actually tag 1.6Alpha?  I don't understand the
second part wrt Ant's website...

What ground work should be done to sign?
In other words, where must public key be posted?

1.5Beta1 preferred?

ok.

Where do you look up the number of hits?

:-))  That reminds me to say another 'Thank You' to
you for taking care of releasing 1.4
