Not sure if this is related,but I did receive the same email and noticed another thing when I went to the web site today.

On the E-rewards home page I noticed a link that mentions a "Special Bonus Earning Opportunity". The link gives me this message:

Each time you earn $25 in e-Rewards Currency between April 20, 2008 and December 15, 2008, e-Rewards will post a bonus of $25 in e-Rewards Currency into your e-Rewards account. This Double Rewards Bonus will be posted to your account within 10 business days following the date you earned the required $25 of e-Rewards Currency.

At least it's something to try to keep their participants (us) in the program, with this I can earn HHonors rewards faster. Without HHonors in the program, I probably would withdraw from E-rewards.

Added to say: shows I wasn't paying attention, OP already states the info I have listed :-(
