Can you explain how a user of the plugin is shown the relevant Facebook terms of use including the privacy relevant bits? I’ve installed the plugin and even with a lot of hunting I wasn’t able to find any relevant information (naturally the terms should be shown on install in any case, but cutting you some slack there).
