Sunday afternoon/evening I attended shveta_thakrar's writing group. I decided on a question and answer format rather than simply reading, and I think that was the right choice. I was able to answer questions about what it's like dealing with professional editors (for instance, I shared my revision letter for the current novel), my opinion on full-time writing versus having a day job, the conventions I like best and why, my experiences so far with sfwa and rwa, and networking strategies, such as making sure to spill something on the editor so they will remember you. Not!
And a bunch of other questions, too. I don't remember them all. I invited them to pick my brain, and so they did. It was loads of fun, and I would do it again in a heartbeat. Also, it was great to meet some new folks and renew acquaintance with some I'd met briefly before. (If you're out there, feel free to email/say hi/whatever, any time!)
