for unknown reasons all emails that i send to comcast.net accounts are bouncing back.
if you have such an email account and need to contact me, please either use a private message in this forum or get a backup free email account, e.g. gmail.com, and email me from that account.
i apologize for inconvenience but the bounced emails just say they were in the queue for too long, no other error message or return code. you may also want to bring this issue up with your email provider.
