I bit the bullet and finally purchased my own custom domain name. www.aliveandyoung.com was taken. But I was able to get www.aliveandyoung.net.
I did it mostly so that I can get around the firewall at work: these catholic school don't allow access to blogger and I often have things I want to get off my blog to use in my classroom.
The old blogger address should still work, but be sure to update your links, especially if you work at a place with an obnoxious firewall.
