Pretty simple. Of the four forums in Real-ish, two are dedicated to creating. I think I should take it upon myself as a person in absolutely no way part of the TV Tropes
Forums Mod Staff to help you guys clarify the difference between the Writers Block and World Building stuff.
World Building: Concept discussion for any aspects of crafting a mythos. They can range anywhere from general discussion of world building principles to your own mythoi and naruto-barney crossover slashfics; this includes highly specific threads, maybe discussing technology like: "Hey, just how badly does my neutron-twin-blade propeller jet space transition Qwib-Qwib FTL drive make anyone who made it past the third grade want to kill themselves?" Yes, that's right, I was mocking you personally.
Writers Block: For the less "creative" side of writing. This section is for critiquing prose, discussing writing styles, etc. I've seen people post threads about aspects of their mythos with no direct relation to writing itself in this section, which prompted me to arrogantly post this clarification thread.
Well, I hope this confused you properly. Carry on!
