In a small play-by-post game, and in every story RP'd in general, the lenght doesn't really do the magic. Interaction, active posts which make other players and their doing feel relevant is the key.<br/>So: it's not the size, but how you use it.  ;D<br/><br/>Don’t feel pressured to make big posts.  8-)<br/>I'm fired up for this game! Spent my evening reading spells in 5e!
