Hi @kwoodall,

The [Add Topic] button is located in a forum. You should click on some forum title to find it, it's not located on forum home page. Only the Threaded layout comes with home page [Add Topic] button.

In Q/A Forums can voting for best answer be turned off?

Yes, just uncheck / disable the "Can vote" permission in Standard forum access settings. The Standard forum access is usually attached to the Registered (simple user) Usergroup for all forums by default.

Yes, just use the Answer button:

Hi @kwoodall

You can use this CSS code. Add it in Dashboard > Forums > Settings > Styles > "Custom CSS code" textarea, save it, delete all caches, and check it (press CTRL+F5). 

.wpforo-post-voting {
    display: none;
}
