Yes, the RP is indeed still open to new applications and recruiting. Don't worry too much about the advanced tag on the RP; as I already wrote in the interest check writing ability (and/or willingness to put in huge amounts of effort) isn't paramount, and not being constantly active is also acceptable as long as you keep us/me informed so that people don't end up waiting for you to post before doing so themselves, and (in extreme cases) allowing some mild puppeting of the character to keep the story moving.

Feel free to throw in an application over in the OOC whenever you like, and to speak up if you need information or advice.
