I think some of the older members of our forums may be having a difficult time easily distinguishing the colors alone.

In the meantime before we can make it fully solid we've made a slight tweak to make the outline a little bolder using this CSS.

#wpforo #wpforo-wrap .wpf-popover i.fa-thumbs-up {
-webkit-text-stroke-width: 1px;
}

The like button changes its color indicating that you've already reacted for this post. I think the color says more than the icon outline:

We don't have solution for changing icons and outlines yet. I'll ask our team to add this in our to-do list, but I cannot provide any ETA for this feature.

When a user hasn't liked it, it shows an outline version, and then when a user has liked a post it shows a solid version.

How would I change the icon based on when a post has been liked or not?

For some context, we have users who struggle to see the different between a slightly different color outline icon, and would prefer it worked like other social media sites.
