1. There is no way to know until when they'll follow their plans, it all depends on how the team manage to become hyper active and work for it.
2. Yes, if you are experienced but I'm not discouraging you to stop. It's a good experience after all.
True, as i said, they are really transparent with their work and updates which keeps me optimistic, will keep monitoring the project in weeks to come. Not experienced enough, i won't participate this time because it's probably a bit late. Thank you for help!
