MyBB Community Forums

Hello, I want to try Flarum-like theme or plugin, which is...

In index, it shows only the title of latest thread (unlike portal.php shows contents as well), and it has a list of forum in a sidebar.

example: https://discuss.flarum.org/

that's a different forum software , that's not MyBB , if you want to have those design and features in your forum then you have to hire a developer .
