So many museums offer this option to their members signing up online. It's a great way to go 'more green' so that the only outreach in terms of renewal that you would need to do with these members is when their credit cards expires.

Adding to this, I would love an auto-membership renewal that has an auto-credit card update as well. We do not have the manpower to sift through expired credit card information. I would want this to be an option in an existing membership program (not a separate membership program).
