This is a guide to exporting a blog off of wordpress.com, to your own site using the application provided by wordpress.org. Some back information, wordpress.org is where the actual program wordpress.org is located, and you can download and install on a server. Instead of hosting it yourself though, you can have wordpress.com host it for your at different price levels for different features. If you already have a wordpress.com account, but now want to move off the service, then this post will help you.
SSL certificates are a pain. Even though they can easily be found now for only $10, they still take a while to get load, and renew. A new service from the linux foundation fixes these problems. LetsEncrypt gives you free ssl certificates that are automatically installed and valid in all major browsers. This service is backed by big names such as Firefox, Chrome, CISCO, Facebook. Which makes sense, a more secure internet is good for everyone. Good for everyone but the people how sell the useless SSL badges. So making a free painless SSL installation program makes sense.
