No. MOA's current hosting provider charges $10/month for a security certificate that tells you nothing more than that its owners are willing to spend $10/mo. for the appearance of trustworthiness, and self-signed certificates cause more problems than they solve. When the Jaways get around to switching providers, they'll move to one that offers a free security certificate and then - without changing anything about the site or the business - it will have an https address. If in doubt about a site, it's worth checking its whois information
for continuity of and transparency about ownership.
