1. -----DONE----- Write pages for all the links in the header and footer. 
2. Copy the remaining blog posts (write them in Markdown).
3. -----DONE----- Add a 'date: auto' feature, which replaces the date with the date when the file was last modified. At the moment, this is done when the 'date' key is missing. Instead, I can add a separate setting for automatically set the date, and just not include the date in the document if the date tag is missing.

4. Create a subdomain for squirrelmail on the RPi, or figure out some other way of making it publicly accessible (same for PiHole).
5. Style the 'comments.html' page using CSS.
