Fishy?

I received an email solicitation of free advertising from some site called michiganbusiness.us. That seems kinda like a phishing-type scam. I inquired of our Chamber of Commerce, and they were not aware of it. I googled it, and I didn't find any scam reports.

Anyone know any different? Is it a free advertising site? Is it worth anyone's time?

A note on old equipment

Is it really worthwhile to preserve old PCs?  I met with a client the other day who requested a RAM upgrade.  Their PC, a Dell Optiplex GX1, was struggling through XP Home with 128MB RAM.  I didn't think you could install on anything less than 256.
There's no point in going to a brick-n-mortar retail supplier for PC100 RAM, so we looked online and found the maximum the mobo will tolerate is 3x256, at $40 a piece.

I suggested they save their cash and apply it to the purchase of something a bit newer.

Nope, when the RAM arrives via FedEx, we'll install it, and they'll be happy.

But is it right?  Good money after bad, I think.
