In all seriousness, just make it look pretty and put time and effort into it. I find it best not to half ass it and put a wall of text; break it up, use pictures, use BBCcode and hiders, it doesn't how great the RP idea may be, it people don't read your stuff then its all for naught no?

I find that interest checks tend to be representative of someone's personality for me personally: people who make good int checks (and OPs) have a lot better standing and draw my interest better than someone who just chucks words on a screen and prays for the best.

I know for a fact that when I do Int Checks, I usually put up the entire OP I wrote up for it with some slight modifications sometimes.
