Oh yes, thanks NP. It is nice, but not exactly free. I couldn't use it when I had free membership. Now I am on the free trial, so I can see it, and it is handy.
I am and thinking about upgrading to paid membership, and noticed it is cheaper to go with auto-renewal. Do you know if there are any problems with credit card / cancelling the service with advfn? Is it just a simple matter of cancelling online, or does one have to spend hours on the phone? I personally don't like auto-renewals, sometimes they are a pain to cancel.
