Hello, greetings. Im excited to finally join up with this community. I've loved everything I've read, and I'm looking forward to throwing in my ideas as well.
It's great that you're excited about joining! If you're thinking about becoming a site writer, you should first create a sandbox page to keep your in-progress works, references, or ideas in development at. When you've got a draft ready to be read, bring it to the IRC chat and/or the drafts forums for reviews so you can make the necessary edits before a mainsite post.
Also, consider polishing up your ideas in the Ideas and Brainstorming forum before drafting! It can help a lot if your core concept is solid before you start devoting time to the drafting process.
Feel free to message a staff member if you have any questions. Welcome to the site!
