I have registered a few names through them about 10 months or so ago, using some of their google aps and hosting. Basically good for family sites and what not is what I used it for. Coupled with gmail, it actually works very well.
I have something like xxxxfamily.net through them. There are about 10 members of my family that use it for
xxxx@xxxxxfamily.net email. Then they just collect all their other email in there as well. One stop shopping. Share a calander, docs, etc.
OK, I like google. I know I shouldn't but they just make it to easy to give them big huggy-wuggies.
