Permanance fail

[leftyjew]

GWU cancelled an email address forwarding service they had advertised as a permanent alumni benefit. I used my @alumni.gwu.edu email address as my permanent address. I changed where it forwarded at least 4 times, but whenever I wanted to be known on the internet, I was [redacted]@alumni.gwu.edu.
That means that now, I need to change all of that. What does that entail?

• Personal life - all of my friends and family know only that address.  I need to update them.  all...
• Public life - my synagogue, my condo assoc,
• Professional life - Resumes, LinkedIn, GitHub, Twitter, and professional contacts have my alumni address. There's no way I can update all of these folks - especially people I've forgotten but who want to keep me in their professional networks.
• Financial life - bank, ZipCar, Pepco, Paypal, retirement accounts - almost all financial institutions who know my email address know that email address.
• "Online" life - social networks: StackExchange, LiveJournal, Dreamwidth, all mailing lists.
• My email address, personal website and domain host use my alumni address as a backup - I figured I could always point it somewhere else if necessary.

What am I missing?

Lessons learned:

1. Do not use an email address of a domain that you do not own.
2. Use OpenId where possible and tie that identity to your personal domain.
3. GW will screw you over.  Even after you've graduated.
4. Permanent means ten years.

What else should I be taking away?

GRrrrrrr!!! SO MAD!
