Why duplicate requests are a problem
Submitting duplicates will not make me more inclined to type a character sooner. Instead, this has the opposite effect––it just adds cud to the queue, giving me more to trudge through before I can get to your request.
Your character will not automatically show up in the directory after you submit your request. I have to manually add them––so they will appear when I get to them.
Requests will also not likely be filled in a timely manner, and some will be typed by guest writers but will be reviewed by me prior to posting.
I don’t write book reviews or promote other people’s books. While I place a heavy emphasis on literature in my typings, this site is primarily devoted to MBTI analysis of said literature, not a critical review of the literature.
