Yeah, my motto for when I write ended up being, "If it doesn't flow, it's a big no." Because I'm a dork like that. Yeah, to me if it feels like you're controlling the RP you probably are or the other person isn't putting a lot of work into it. It's especially hard because when I start writing, oh my Lord of the Rings is it easy to get carried away. So when I look at it and realize how long it is, I end up completely restarting it. Yeah, and I can't stand people who replace numbers for letters in RP or storytelling. Why not just type out the word? I agree with that concept as well, write it like you would have it posted or published, because it makes you think about what you're writing.
I'll keep that in mind as well, as I often catch myself using the wrong tense XD
