although I am also still a 'newbie' here, welcome!
I have been part of the organisation and staging of an original musical and wish you the best of luck and patience! It is a big task! Break a leg!
I have been in this forum for a bit and some of the advice from here is great, but like most of everything some is not so. But the great thing is you can take it or leave it at your will.
Top tip: One of my first mistakes was to post a large script, even though 'IThink' people have read it no comments have been posted. Demoralising! I got told 'gently' by one of the moderators, that first timers rarley get read if it is too long!
Hope you enjoy the forum, anytime you wan to chat,
