We're here, name differences notwithstanding.
We do counsel our customers to set no-export on their more-specifics,
and we're happy to show them how or set it up for them. When I see
customers on the CIDR report, I make sure they get a phone call to
explain why aggregation is good and how we can help.

First email sent to USDA Feb 2001 when they had 277 prefixes. No answer ever to any emails. I tried their upstream - UUnet - also with little success.
