Yes, you can have threads open to the public
Get an account with a webhost (e.g. Web Hosting – Secure, Reliable and Fast, there’s tons of others). They would let you register a domain name and would give you a cpanel (control panel) account thru which you can control your account and/or install those CMS packages that I was talking about. If you want to see what it looks like PM me and i’ll set something up for you (I’m not affiliated with Dreamhost).
