Can someone put me in touch with someone "up there" in the
security realm at Google? (sorry for the noise)
In general security vulnerabilities in applications should be reported
following the links at http://www.google.com/about/appsecurity/ For abuse
issues, there are usually links within the products.
If your question isn't covered by any of that, I can probably help. Feel
free to ping me off-list.
