Managing Subscriptions

I've realized a tactical mistake I made in signing up for information and knowledge using my work email and now that I am changing jobs I have to figure out which enewsletters I want to still subscribe to. However, its not easy to change your email address on most of these enewsletters. Most ownly offer the option to unsubscribe - what a lost opportunity for them. A few let me manage my subscriptions but not change my email address. And some have allowed me to change my email and then they send an email to the new address and I've had to confirm - even though I had to login in the first place to change the information.

If you want readers, make it easy to subscribe and manage their accounts.
