Have yourself a good look around. CB is full of great information. Can you tell us a little more about yourself? Are you currently in HS?
Followspots are a good stuff, I've done them twice for a musical and then a lower school play at my show.
Feel free to go take a look through old topics, and post anything that your wondering about (you may want to check if it already exists first) but everyone here is always willing to answer a question, and you can always learn something.
Never really thought about the breakdown of good info versus frivolity before and whilst I would guess it to be closer to 90/10, you have a good point.
Besides, what do they say about all work and no play?
