I used to do e-rewards a lot, but I got tired of the surveys and let my account lapse back in 2014. I occasionally receive "We want you back!" emails that offer me HHonors points to rejoin, but I haven't bitten so far.

One of the (minor) irritations for me was that HHonors was the only hotel program that I could redeem points for. I assume that's because I originally signed up via a Hilton invitation.

Does anybody know if there is a way to sign up such that I can redeem for all hotel and airline programs?
