[quote=@Kuro] Player/Player, rather than the GM/Player style you mention. Both sides work to develop the world and continuously push the plot along with every post. [/quote] ^ This. It's more fun to collaborate and build together than have one person do the work. Sometimes the original idea is mine, sometimes the idea is theirs but we both have things we toss in the pot. We generally build the setting and the beginning plot first but leave it open-ended so we can have fun along the way. Also, don't be afraid to reach out if you're stuck. Kind of like "Hey, I don't really know where to go with this next post. Where or what is the next point/place/goal we're trying to get to?" Your partner may be able to help. Communication is key to a lot of things in life. That includes your writing and your writing partner.
