I prefer not to since the wiki can become cluttered with old and out of date stuff, however, I won't stop you from adding your own characters. If you update your wiki page, then it's a beneficial thing. If you forget about it and don't update them then it becomes a non-beneficial thing.
Up to you if you want to use that service.
