I’m away from home and have been for the past four weeks, so no paper mail. I took care of all my expected bills in advance. All my paper records are at home, and I can’t do any of this stuff from memory.

A billing entity says I’m past due to renew my domain name (which includes my email). The billing entity is businesswebsystemsource.org, a name I don’t recognize, and I thought this domain name came due in December.

There’s something else funny about this so-called renewal, so of course I’m cautious, but I also don’t want to lose my site and all its contents and all my nonpersonal email.

Do you know how to check if this is a legitimate entity or a scam?
