Thank goodness, I'm too much of a filthy casual for writing of such magnitudery

Personally, I don't think a standard length matters. I've written stuff as short as one paragraph in the same RP where I wrote something like two pages long. 

What matters most is you accomplish what you're trying to do. I don't need a 1000 word essay on how your character answered 1 question and moved a cup but at the same time I don't want a single paragraph in which your character settles an epic duel, saves the princess and promotes a democracy based government to a previously community country.

Just write what feels right :rock
