To our knowledge there have been no changes occurring with the software on the forum board. Are you using your comcast email address for your primary PNP address? If so, we have had issues with comcast in the past blocking automatic email notices. I understand that you have been receiving them until lately, but I would double check and make sure that email@example.com
is added to your safe list. If it is, and this problem continues, please let us know and I will ask our technical people to look into this further. Thanks for volunteering, we want to make sure you get your messages!
