I've seen a couple of posts of late regarding Mailing Addresses in the US.
As doc has menioned the problem with using mailing addresses is that you end up getting a LOT of "junk mail".
However, if enough people are interested I would be willing to get a PO Box at my local post office (@ annual cost of $30 - 45) and then have my office forward the mail as needed to the intended receipients. The costs could be shared or figured out some way. I am sure something would be proposed.
This is just a thought but if anybody is interested please drop me a line.
