Hmm, I love the idea of acting and really enjoyed it at school but no idea how good I am, can you be crap and be in these groups for a laugh?
Haven't thought of taking a class, that sounds quite fun actually.
Some take it quite seriously, but others can be quite relaxed. Have a look around and see if there's anywhere local to you.
Don't know much about this but don't know if Andram has a list of groups that you could explore? Or just google it
