Well the list was planned to be at least partly where the work takes 
place - not as an announcement list where updates from elsewhere are 
posted to.

In the end it turned out that the work is being done elsewhere, mostly 
by Matt who is on this list but doesn't usually participate in the 
discussion. Maybe that's because he hasn't even been asked whether he 
wants to be on the list in the first place.

There are a few other technical things in connection with the change, 
not all of them are directly "rebuild" related but if anyone is looking 
for ways how they can help:

* all applications that make /history or /changeset/full calls or try to 
access individual object versions will have to be tested whether they 
work with the now-changed API responses (most visible change is "holes" 
in version numbering)

* the process that generates the full history planet must be changed to 
leave out "redacted" versions

* any consumers of the full history planet must be aware of the new 
situation

* our tile server needs its very own rebuild, possibly a full import 
after the change is through. all users of the tile server will probably 
need to change their attribution slightly (-> should we evaluate referer 
logs and build a team to send out messages to people?).

* someone could grep through the SVN repository and find whether 
cc-by-sa is hardcoded in places and fix that (not automatically because 
it might not always refer to OSM)

This is just off the top of my head and probably reduplicating a list 
that must exist in LWG somehwere, so if someone is already working on 
one of these just say so...

Bye
Frederik
