I'm surprised that members are still concerned by the 'not secure' messages. I thought Cedric had explained it very well, with reassurances:
Hi all,
As mentioned here a few pages back, the "not secure" banners in your browser only mean that this website is not using the https protocol. The technical team is working on this, but since it is a pretty big operation this may take some time. The banner "not secure" is therefor not really a problem or safety problem with the website as such, only that traffic between your computer and the shipspotting.com server is not encrypted. This is not a major issue since no financial or confidential information is exchanged here.
I hope this makes things clearer for everyone.
