In GNOME we use IRC to hangout together and the newcomers mailing list. In the #newcomers chatroom and mailing list you can ask questions while following this guide.
Patience is your friend.
It can take time before a fellow contributor can help you. Please provide as much information as possible about your problem and don't message via private messages - you can use the #newcomers channel.
We are like a big family of all kind of cultures and backgrounds. We want a safe and comfortable community for all so you will feel like at home.
Take the initiative and be self-driven.
GNOME contributors find and decide to work on tasks on their own. GNOME is driven by people like you who takes the initiative and create awesome things!
