How Best to Represent Theatre Activities?

<p>I have been involved in school theatre programs since 6th grade and have performed or assisted in 13 mainstage productions, not counting one act festivals and talent shows. To me, just using one tab on the Common App's extra-curricular section and calling it, "Theatre-4 years" doesn't seem to do it justice.</p>

<p>If you have an activity that has lots of large "sub-activies", what is the best way to portray it on college apps for top 20 institutions? Thanks.</p>
