A. Friend request "Wizardtho Seventy-nine" on Facebook and private message with your nick. You will let you onto my wall, where I always notify "Story Update Status" posts when I add something new.
B. Request being added to "Bella Macleod's Fanfiction Group" on Facebook. Here you'll be apprised of any site news, as well as story updates when they come out.
Those are your options for now, as the site will not have those options for at least another year.
Thank you,
Wiz
