Thanks Graham. You're right.
In our neighborhood, we used to deliver notices to our homeowners from
the homeowners association. It was usually a one page letter
concerning our neighborhood, brush pickup schedules, etc.
The postal service advised us on this, along with other matters
concerning the mailbox, which really seemed ridiculous, but, alas,
they take this stuff seriously.
Just a bit of advice to Rich. Ask your local postmaster about this.
Just because you bought the mailbox, maintain the mailbox, and have to
replace the mailbox when it rusts out, doesnt mean you have any rights
to modify it. <mad>
It;s really a shame that people want to speak with authority when they
have no idea what they're talking about.
