For reasons unknown to us at SCC, it seems that SCC members who are AT&T users experience issues with emails and personal messages when using our forum. This is not unique to SCC and several other internet sites are reporting the same issues. Todo10, the company who helps us with the forum and hosting, have file a complaint with AT&T but we are not convinced AT&T will do anything about it. The only way around this is to register and use another email address not connected to AT&T. We are sorry for any inconveniences this might cause!
