Have you ever gone to your local community theatre?  I work there when I'm not taking classes in school
I have not but  Community theatre refers to theatrical performance made in relation to particular communities
yes - do other communities have similar theatres or are they different depending where you live?
It should be base on community. It also refer to theatre that is made entirely by a community with no outside help,
yes - we produce everything ourselves!  The ticket prices are a lot less than 'real' theatre, too
Community theatres range in size from small groups led by single individuals that perform in borrowed spaces to large permanent companies 
what's the smallest size?  We've had 5 people once! 
It differs, Many community theatres are successful, non-profit businesses with a large active membership
