Hi!
I'm a moderator, not an administrator, but I can answer this question for you. We LOVE to have authors add links to the forum in their stories to the review or discussion threads for a story, and I'm equally happy to have you add that link to a review, so folks can know that they can come and chat with you and magusfang here.
The Fan Fiction threads, where most of us post review reply threads, is open for anyone to read and reply without registration for the forums. It has to be a registered forum user who starts the topic, but magusfang is certainly registered. The Writers Corner threads are for forum members only, so those discussions would only be open to other forum members.
And as an author, can I say thank you for being the kind of reader who wants to generate discussion and spark interest among other readers? That's the kind of thing we all love to have happen, so thank you!
