It might be easier for some users to view the forum in a different theme, and I have installed several different themes for you to use.
To change the current theme (Default), choose Profile>Edit Profile>Settings, then scroll down until you find Forum Theme and choose the theme you want, then confirm by clicking Save Account Settings at the bottom of the page. The change will be made when you navigate away from that page, eg by going to Active topics.
By all means, post positive or negative comments here; you can use the same route to revert to the Default theme if you don't like the new one.
For those who are interested in seeing all the themes that are available for the forum(s), see:https://www.proboards.com/library/themes - any suggestions for a particular theme to be added will be considered.
If you stay positive in a negative situation you win
