Have you come upon a link that looks like file.md?
.md is the top-level domain for Moldova! Fascinating history and location!
Since these fora have that hot pink vibe going on (love it!) it can be dissonant to see a markdown file turned into a link to nowhere. So <code> it! Use backticks around the file name, and it will instead look like file.md.
Instead of file.md, type `file.md`
