You will find two kinds of links in the text of wiki pages. Internal links go between wiki pages. External links go to other places on the internet.
Internal Links
An internal link will search a neighborhood of the federation for the page named by the link.
Hover over an internal link to see what servers it will search and in what order.
Hover over a page's flag to see where it is stored. Notice colored boarders indicating various sources.
An internal link might find that you've edited a page and have that page in your browser local storage. The link will show you that page instead of any other.
Hover over the page's flag to learn were it was found. Border colors are added to pages as follows: yellow for local storage, blue for remote sites, and, green for plugin documentation.
Internal links are always the title of the page they reference. This sometimes leads to awkward grammar but has the advantage of presenting meaningful names.
External Links
An external link is like most other links on the web. When you click the link you go to the referenced site and start browsing there.
External links typically open the referenced page in a new browser tab.
External links are often just a string of words that has nothing to do with the title of the referenced page.
