+# BigBlueButton notes
+
+You can connect to your BigBlueButton room
+beforehand. All the EmacsConf meeting rooms are
+set up so that anyone can start them, and the
+check-in email has the moderator access code so
+that you can connect as a moderator. Then you can
+check your audio, your webcam (optional),
+screensharing, etc.
+  
+Sharing multi-monitor setups can be tricky, so
+you may want to arrange your windows so that you
+can share just one screen or one window.
+
+Sharing your microphone audio should be fairly
+straightforward once you give the browser
+permission, but sharing system audio from
+applications (as opposed to browser tabs) is a
+little tricky. It's probably more straightforward
+if you use Google Chrome on Windows or Mac OS;
+there'll be an option to share system audio. If
+you're on Linux or other operating systems, you
+may have to look into how to configure your sound
+system to use your system audio monitor as the
+microphone or create a combined source that uses
+both your system audio and your microphone. For
+example, in Pulseaudio, you can change the
+microphone used by an application by unmuting,
+opening PulseAudio Volume Control
+(pavucontrol-qt), going to the Recording tab, and
+changing the microphone to the system audio
+monitor.
