[@Lucidnonsense] We know you're new here, so just keep this information in mind:

When you look at roleplays, look at the top of the page where there's a little thing that says: "Join status:..."

If it says apply, then it's open to join. And as you can guess, full is that it is no longer accepting new players; at least not for the moment.

You are always welcome to stalk the page in case someone leaves, freeing up a space, just don't count on it.
