We will be launching our premium user upgrade V2 over the next week.  The new features enable users to add contacts to an address book, set reminders, administer their account and see if theiur cards have been picked up yet.  It is still free and always will be so keep an eye out for it.  We will be sending an email to the base once it is fully working but we are just trialing it at the moment to clear all the bugs and also to make sure that the site does not slow down too much.
