Have phoned her to find out if the 24 hours delay is cool, and she's ok 
about it.  Before making it clear that the reason for the call was to 
ask if a 24 hour delay is ok (and also telling her why... "it's a good 
"quick" trial project for the new Advocacy and Marketing group and the 
collaboration software"), she grabbed her notes and started reading the 
questions off to me.

Gut feeling says that she's asking these questions because she's not 
sure what else to ask.  So we should probably answer them directly, but 
also it might be a good idea to give her some other stuff so she can 
write something that sounds interesting for the readers.  ;)

The readers may be reasonably technical, as it's for the site, but she isn't.

Maybe a bit too formal?

How about:

The "92 scheme specification" is the American National Standards 
Organisation (ANSI) SQL92 standard, which specifies the SQL query 
language used by most major relational databases (PostgreSQL, Oracle, 
DB2, Sybase, etc).  Schema support is one of the parts of this standard, 
making it easier for [blurb], and to migrate from other (often 
commercial) databases to PostgreSQL.  PostgreSQL has actively been 
adding ANSI SQL features for many years and is now one of the most ANSI 
  SQL compliant databases in existence.  [is this true?]  This makes it 
easier for PostgreSQL to interoperate with other ANSI SQL compliant

Needs a bit more explanation, really spelling it out for people.  i.e. 
"There are no license fees of any kind for PostgreSQL, and you are free 
to modify it however you want, and don't even have to share your 
modifications with anyone.  The only thing you have to do is make sure 
the BSD license and copyright notice are included with any versions you 
do distribute."

Cool.  :)

Maybe we should use this opportunity to build anticipation?  Something 
like "Because we'll be adding native support for Windows, Point in Time 
recovery, and other advanced features in PostgreSQL 7.4, our initial 
target date is around April 2003".

Does this sounds like an ok approach?
