Dave W's [Signpost Rep] above, is a classic example of the problem with Signpost; you can't just cancel the service. They bill you in advance, will not refund what they have billed (even if you quit using the service), and make it very difficult to cancel. You can't just click a button, or send an email, you have to endure a long sales pitch by a tricky, and very aggressive, sales associatte. Best to just stay away!
