Verifying against the live site and live WHOIS/DNS…
Common questions
Is ccl.net legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns ccl.net?
Nobody has completed AboutUs's owner verification for ccl.net. That's true of most sites here — it isn't itself a warning sign.

2006
The Computational Chemistry List (CCL) is an e-mail exploder which allows computational chemistry researchers from around the world to exchange information and experiences. You do not need to subscribe (i.e., get CCL messages) to post to CCL, but your e-mail address from which you post needs to be "blessed" by the administrator. It happens when you post your first message to CCL.
