Meat, I have added a few test addons for you to see and decide if you want them or not. Plus links to how to change or delete them yourself if you want.
For this :https://hostagerp.mistforums.com/post/1000774/edit
Find a widget on the forum page with info about the widget and the button.
For changing HostageRP in the top left to a picture instead; Go to Admin -> Design -> Logo
For changing the little blue and white logo in the very top left go to Admin -> Design -> Favicon
To add emoji's: https://hostagerp.mistforums.com/admin/module/7/edit
To create more Forum post topics/threads In Admin go to layout and create a new Bracket then posts within that are categories.
