Hi folks,
We have enabled a classic “Light” theme on the forum which removes most of the bells and whistles that you may consider as cluttering the homepage.
You can select the theme by going to your User Preferences → Interface → Choose “Light” under Theme.
We are also working on making another theme that would be similar to our default one, but only removing the right sidebar blocks and a few other things. We will let you know when it becomes available.
