Topic: Welcome to the Young Adult & New Adult group
We've recently renamed/revived this group as Young Adult & New Adult, and it's intended to be the go-to group for writers of both genres. If you write fiction that spans multiple genres and you're not sure which group to use, the site allows you to post stories to multiple groups, so feel free to use whichever ones you think are appropriate.
Authors of horror-style tales of vampires, werewolves, and zombies are advised to use the Fantasy, Magic, and Sci-fi group. That group covers most stories of the fantastical and has traditionally had the more active forum.
Although there are no strict rules for this forum (except be kind), if you'd like to use the forum for brainstorming with other members about your stories, the preferred practice is to create a brainstorming thread (i.e., a "topic"), usually one per story, named Story Name by Member Name or similar. Group members can then use that thread to discuss the named member's story. You can keep updated on discussions by subscribing to the threads that interest you, or simply check out the forum from time to time and comment when the spirit moves you.
Other topics/threads for other purposes are welcome as well, including requests for reviewers for new stories. Please be prepared to reciprocate, though.
If you're new to writing or new to the site, please also join the Writing Tips & Site Help group, where experienced authors and members will do their best to answer your questions. Be sure to check out the forum post in that group on how to maximize the number of reviews you get.
