+  <abstract>
+    <p>
+      Finished the bash unit in CS246 and still don't see what's great about
+      Unix? Want to gain some more in-depth knowledge, or some less well-known
+      tips and tricks for using the command line? Unix 102 is the event for you!
+      Fatema is "kind of successful" and "knows things about Unix" and you
+      can be too! Topics covered will be: users, groups and permissions, ez
+      string manipulation, additional skills, tips and tricks.
