I have signed up for email information from Hhonors and consider it as a useful source for information and ideas.

Yet, there is one thing which I find rather annoying: Even though I live in Europe, I get all promotions, including those for US residents only - and there is a lot of those. The result: If there should be any interesting promo in US which is open to me, I'd probably just skip it. Bad luck - for Hilton as for me.

It shouldn't be a technical challenge to setup some filter routines to match promo and residence.
