For a little insight into how we designed our website, check out: The Keys to Designing a Successful Theatre Troupe Website
I use weebly, here are my drama club and class web sites:
What a great idea to get high school students thinking about a school theatre website! There's such a wide discrepancy in high school theatre websites, from "Gold Standard" to non-existent.
School theatre websites are important to have for a variety of reasons and uses. In fact, one of the assignments for the students (high school Drama teachers, in this case) in my online Theatre Management class is to create a functional and useful website outline for their school theatre, or to come up with ideas to improve their existing websites. (We don't get into the technical side of creating a website, we primarily address content.) They all do awesome jobs, so I'll pass this on to the students from the recently ended session, and suggest they contact you with their information and ideas.
