He had read some of the groups' work and mostly advised on writing logically. For example: No need to describe every detail and context as the story happens because that's not how humans typically live. The story should unfold just as our senses observe life unfolding. Tenses also need to be consistent... but I didn't quite understand that, and asked if all these "rules" around the logic of writing apply to poetry. He said some rules do but not all.
He did also say that if you cannot live without writing, don't write. I'll be thinking about that one for a while.
