I think I would make a separate space in a person’s profile for his/her series hyperlinks. Like, allow html in the profile so you can just click and be there. Also, I think way more people would follow series (plural) if there was a feed to a the whole series that let them know when a sequel was published. (I know I’m probably supposed to write that in a ficlet, but my brain’s kind of meh).
