I agree 100000000% with the use of colors. It's pretty much impossible to read the content. You're essentially scaring users off.
I do really like the set up of your forum list though, good job there. Your homepage also isn't that bad for a landing. Although it can use some more text and photos perhaps. I would take your homepage and forum list structure and scrap the rest design wise for 2016 and i'm sure you'll do great
