1) Where can I find various wpforo themes?
2) How can I install them?
wpForo has only one theme ( Classic ), this theme has 5 color styles, you can choose them or customize one of them. So you don't need to install any theme, your current WordPress active theme is enough. wpForo is compatible with almost all WordPress themes.
