Hi Liat
Happy to add you as a writer to the publication. As for the series, as they've already been published you won't actually gain anymore views than what is currently dribbling in. They would just be housed in the JPF but still dated from the day they were published.
There are ways around this (editing as a new story and then submitting to the publication) but they would have to be significantly different to get round Mediums rules.
Will add you as a writer and look forward to any future submissions.
Thanks
Reuben
