Use two fingers and spread them to zoom in, the opposite of zooming out (pinching). That makes the text larger.
Oddly, I can't pinch-to-zoom on the AC Forums website on my 2013 Nexus 7. It's running the latest Chrome version, and it's showing the full desktop layout (not mobile layout).
Ok, if I tap Menu>Settings in Chrome and tap Request Desktop Site, that allows me to pinch and zoom. I think that if you don't Request Desktop Site, it shows you the desktop layout, but doesn't allow you to pinch to zoom because it's acting like it's a mobile layout.
