I have a lifetime account at SDF, and I've set it up as an emergency email address of last resort. If I ever let my domains and all other freemail accounts expire (perhaps I'll get hit by a bus and stay in a coma for 10 years), I'll try to use my SDF account to regain control of my online presence.

Well, I'll actually have to do a few more things in order to make that possible, but at least I think SDF will last longer than most other services of its kind.
