I was just going to post that a reply to my e-mail mentioned visiting the site. It also said that if you wanted to be on the mailing list to send your name as it appears on the contract, your membership number and your e-mail address.
TwirlerGirl, they do send some "semi-sales" info but it's usually things we do want to know. Items like the recent e-mail announcing HHI was approaching sell-out with only a few Use Years left for add-ons. They have also sent reminders when banking deadlines are approaching, notice of new hotels added to Concierge, etc. I can't recall anything that didn't have at least some info I was glad to receive.
