It could be set up in a few minutes. I used to be a mod on a yahoo group. I could set it up if enough people would be interested in using it. You’d have to have a Yahoo account sign in username. You can also set it up when you join a group (if you want) to have it email the postings to your email address so you don’t have to visit the site to read postings. You can have it email you posts individually, or once a day as one multi-post message.
