Activation Email

I thought I'd already activated my account the first time I got a notice about it.

The second time I got a notice, I logged in.  I didn't see anything about activating...it was just a normal login.  I did notice that the billing address was wrong. (It should not be the same as the service address.)  I fixed it.

Today, I got ANOTHER notice about activating.  I logged in again... This time I noticed that the billing address reverted back to the service address.  I changed it again.

What's up with these activation notices?  Do I need to do something else?  It's not obvious.  I did a search for activation and it showed the process I went through originally.

Thanks,

Jane
