Don't worry, ask anything if you're wondering. Bunnying means different things to different RPers, but on PC it mostly means taking control of another player's character. I'm allowing it slightly if you've asked the other player beforehand in a certain situation.
Example could be to write a conversation with another player's char in your post, or writing about the other char taking an action, going somewhere, dying etc. There are many ways to get around it and still write quality posts.
