We've just implemented our reminder system about paying your bill. You'll now see an alert bar just below the header and, if you have fees more than 3 months overdue, an interstitial screen letting you know.
Until the end of this year, reminders are the only consequence of having overdue fees. Starting on January 15 of 2008, accounts with fees that are 2 months overdue will not be able to list new items, and having fees 3 months overdue (or greater) will have their accounts suspended. We'll always contact anyone with overdue fees several times beforehand to make sure things are OK and see what we can work out.
Once again, until the end of this year, reminders are the only consequence of having overdue fees.
