Uhh, yes it is.
In fact, the sticky post here:
Literally says this:
2. THIS FORUM IS NOT FOR FAN-MADE FICTION
Despite what the name may imply, the Story Forum is not for sharing or discussing fan-made material. It is for discussing officially sanctioned lore/stories only. In short, if it doesn’t have a Blizzard logo, it doesn’t belong here. That doesn’t mean you’re forbidden from linking any fiction you may have written (it can be useful in explaining your position on a topic, for instance) or posting the odd paragraph; however, copying large amounts of text or creating threads specifically for any fiction you’ve written will be deleted or moved.
If you want to discuss your own material please take it to the fine folks at the World’s End Tavern Forum (otherwise known as the RP forum).
So, I’m sorry, but Micah is right, this forum is for discussing official lore and the stories that Blizzard has written. If you want to discuss your own RP and your own creations, then the best place to do that is the World’s End Tavern Forum, aka, the RP forum.
