Deleted A more modern web application will be preferred by search engines. That's just how things are. This platform properly supports HTTP over TLS. That alone will make it preferable.
FWIW they played with self-signed certificates, which made the browsers really scared (which is bad design of the browsers, since they should be more scared of no certificates in login). Somebody must have complained because they backed off to no-certificate again. Which is silly since a real certificate from a real certificate authority can be gotten for free or for cheap and it actually same hassle than self-signing these days.
CyberGene Well, I don't know. I'm not even sure I know what his username on the forum is, I've never communicated with him and I've only heard people referring to him as Frank. I feel slightly uncomfortable to contact him directly like that.
You can find him in some of the most "high profile" forums and "sticky" threads (e.g. instrument sales) and in the user list. His username has the "owner" badge (where some people have the "gold", "platinum" etc).
But I understand your unease and I don't intend to push you to do what you don't want.
