Trevor,
Sorry I didn't see this posting. I haven't conditioned myself to check the blueboards for messages. Are you still looking for a group or a partner? I am the regional critique coordinator and collect names and try to connect writers with one another. I will put you on my list as well and can contact you when I hear of other people looking to form a group or find a partner.
Also, you can join us at our regional Zoom meetings (AKA Shop Talks). I know many writers/illustrators that have made critique connections that way. I think there are a few sessions left before summer vacation but we will start up again in August.
