Hogwarts Houses are a big deal on our forums; there are many house-specific events and competitions, and the four Houses compete throughout the year to take home the House Cup.
Many of our members have requested an option for authors who are also on the HPFT forums to identify their house, to facilitate house-wide events. After putting up a poll, we found that a large majority of members wanted the option, so we've added a category for it.
Please note that you will have to go in and add the tag to each of your stories manually; however, you will not need to edit your chapters or put the story back through the queue for it to be added. :)
