I have 4 active domains. One is my surname, so it’s for family stuff, one is for our family business, and two are for personal blogs that I no longer update. I probably won’t renew those two. I also had two other domains that I have already allowed to expire since I don’t use them anymore.

As for my level of expertise, I would say I’m intermediate. I have used two registrars and have transferred two domains from one to the other. I know how to change MX and CNAME records for both registrars, and I am using Google Apps for all four of my active domains.

BTW, GoDaddy sucks. :p
