+      Hello, I'm Marcus, and I'm in my fifth and final year!
+      I'm responsible for minuting our meetings and making agendas publicly available on our website among other things. 
+      My interests outside of Computer Science are movies, cars, planes, '80s music, laserdisc and other nerdy stuff! 
+      I'm normally around on Discord so feel free to message me!
