I am very proud to announce that tier's community has a brand new custom dog theme. The creator of the original theme years ago kindly re-wrote it for MyBB 1.6.9.
Why is the background white? I think it stands out too much, and it's valuable space that could be put to use in adding to your niche.
The forum icons look a little funny. It took me like a minute to figure out that it's a dog, but maybe I'm just slow.
The black text on a dark red gradient is kind of hard to read, that should be changed.
It really kind of looks like a default MyBB theme to me. :/ Sorry, but I had to be honest. Here are two ideas of how you can really extend the limits of a forum software.
