Yep, what Nobillis said. I had to go to the local courthouse and register "Fox Tail Hosting" as a company, then use that as the organization name when creating the certificate. It also isn't shared. When I bought it, it was good for 3 domains of my choosing, and when generating the certificate, I chose to have foxtailhosting.com, www.
foxtailhosting.com, and community.tulpa.info. You can read the domains listed here
, as well as some other neat things about the certificate (such as the chain).
As for the grey triangle, I'm just happy that we're no longer having that "This connection is not trusted, click here to continue". There's a few non-SSL entries/images being loaded through SSL (probably the lolflash banner, some users' hotlinked avatars). The passwords that you enter and the webpage text is still going to be encrypted though, even if some images are not.
Edit: The warning should go away on the main page now (I fixed the lolflash banner), but on this page it'll still show up since my avatar is hotlinked from imgur without https.
