Something like
1) Join our MeetUp group and RSVP to the next 101 orientation
2) Quick and easy registration to our site so we can have your eMail address
3) Check our Existing Active Working Projects (A, B, C,)
4) ......

首先审查现有的活跃工作项目，以及当前的网站注册和入门流程。完成的标准是：网站拥有一个易于访问的 Newcomers 页面，其中包含涵盖这些步骤和活跃项目的具体、可执行路线图。
