This is the right place to ask questions.
If you're looking for feedback, then The Writing Workshops is the perfect place. You can put up your work in there. The Workshops may not be accessible for a few days as you're a newbie. I can't remember, but you might need to have been a member for a bit and posted a few times before you can get access to that part of the colony, I can't remember - it's been a while since I joined. Anyway, you will find lots of helpful folk in the Workshops who will be happy to help you. We encourage new members to give feedback on other people's work before they actually post their own work up for critique. For various reasons; check out Agent's Pete's threads in there about how to use the workshops as well as the Litopia method of giving and receiving crit. It'll all become clearer. Also, members are more inclined to help you if you have built a relationship with them and if you dedicate some time to help them first.
Cafe Life is used for general chat. The Writer's Room is for anything writing related. We also have the Backroom which is only accessible to paying members. Paying members can also participate in the Huddles. Huddles are our weekly Zoom meet ups, where we discuss our work (you can bring anything up to 1k words, like a first page, a synopsis or a blurb), and where we talk about writing industry stuff, and where we socialise.
Any questions, ask away. To get most out of this place, get stuck in. You'll soon get the hang of it.
