Yes, CitySeen knows that you've been meaning to do it early this year. We also believe you when you say that you'll get around it before it's too late, but we're just letting you know that, well, you're starting to cut it pretty close. No, CitySeen's not talking about buying Christmas presents for your mother-in-law. We're talking about the post office's latest posting days. CitySeen is here to remind you that, for those of you with friends and family in the US, the cut-off date is today. You've got until Tuesday to come up with some bons mots for your friends in France, and Wednesday for those in Britain. Canadian relatives will have to settle for an e-card, because the snail mail deadline is gone.
