I have been using skype-to-skype over the computer for several years now. I recently tried to add a couple of new family contacts, and they have also sent requests for me to be added to their contacts list. As far as we can tell, none of us have been able to receive these requests. The email addresses are all correct and up to date, I've checked the spam box, and still the bubble on skype says "pending contact request." As recently as this past summer, I was able to successfully add a new contact. Any suggestions as to what might be going on here?
