Ok, tell me the regular expression that you would match on in the log 
file.  I'm not as good as you are at regular expressions.

I was trying to match on the processed results in webalizer, since I 
didn't have access.

I was told that as well.  It's been 7 months.  Is the data still being 

Of course these problems can be fixed.  And probably fixed pretty 
easily.  But it proved easier to put things in SF than raise this high 
enough on the priority list for zope.org to get it done.  Hopefully 
you'll have more luck, cause we need download statistics!

Ok.  Show me I'm wrong.  I didn't have login access to the box where it 
runs.  I know that you can configure webalizer to keep more data, but 
all that I had access to was the info in the web interface from the 
reports that were produced.

Do you think you can tell us how many downloads of Zope were there in 
2002?  That would really be helpful marketing information.

I sent a full writeup of what I did, and the challenges faced, to geeks 
in June.

Why wait?  Even if NZO were up today, and even if this new, extra work 
were also done, this would still be good for everybody.  The only 
downside is that, a few times a year, someone needs to update the 
download center.

My email at the top of this thread explained this:

Based on the agreed decision to pursue this, Sidnei and I said we'd do 
some work and come back with the results.  Well, it looks good and we're 
ready to take the next step:
The next step is to get this woven into the /Products page, which could 
also use some sprucing up.  We hope to get this done soon, in advance of 
the 2.6.1 release.

Sidnei and I promised on this list to do some investigation and report 
back.  We did the investigation, we're now reporting back.

Changing your question to where the links will be, I'll put them on the 
/Products page this week, along with an improved organization and 
presentation of the download options.
