As often as you like for welcome calls, sharing, and encouragement (for yourself & to encourage others in the community).
As much as you want, especially when new. And when you are ready to contribute and share in leadership opportunities, I am so excited to learn more about your area of expertise.
Posting about your projects (we want to see what you are doing!); checking out & interacting with newly added content. Daily responses to questions as needed. If you know the answer to something... hey, we are all learning together.
