(CC'ed on this reply). Clark said last month that the gnuplot.info domain was set up "on ten year pre payment with auto renew". I don't know whether that includes subdomains or not. Please excuse my ignorance. I don't even know what a "certificate" means in this context, or how it fits in with domain registration. Anyhow, sourceforge supprt has acknowledged the request I made to them to enable https for gnuplot.info so that may yet take care of it. If there is something else I should ask them for, please let me know.
