Write 500 words and bring it in to show the group. Sounds simple, right? But a little scary?
That's okay, we all feel that way, even seasoned professionals (or so I'm told). The purpose is not to show off or to judge others harshly but to get comfortable with sharing your work and hearing feedback.
So bring in a piece of your current project (or better yet write something new), read it to the group, get a little constructive criticism: what people liked, what worked and what didn't, suggestions ... and let's see what happens.
(Note for newcomers: We actually meet in the Atrium, next door, but access is through the coffee shop. If the coffee shop is closed then there is a security guard at the Atrium's Blanshard St entrance who will usually let you in.)
