Sometimes when I see a link on a page, that page connects a URL to text to bring you to a relevant site or page. That's all fine and good, but if you're connecting to another page on this wiki, it's unnecessary to copy and paste the page's URL.
Instead, I suggest if you're going to link to this wiki, you use double brackets [[ ]] as opposed to single brackets [ ]. Just type the page title in the double brackets and there you go. Instant linking, and less clutter in the source section of a page. Else the link button in visual mode (the one that looks like a chain) also works, and is recommended when the text you want to display and the page title are different.
Failing the link button, you can use | (upward slash, I don't know what it's really called) to make the display text and the page title differ. For example, if you want to link to the wiki's page on the Game Grumps series as opposed to the page on their channel, you would do this:
Game Grumps (series)|Game Grumps
But with double brackets, of course. I left them out here so it wouldn't actually create a link. Happy wiki editing.
