[i]Characters sheets are only as useful as you make them out to be.

Depending on the plot of your roleplay, it makes sense to have a detailed character sheet made up. Like Jojo mentioned if your plot involves people that know one another previous to this situation it makes sense for you as a writer to tell US this information before the IC. Sure, some of the stuff is going to be made up a long the way as part of the fun of the IC thread; but some of it is so that you and your group know what is going on before you even get to that point. I've seen roleplays work with small detailed character sheets too- if you don't need to know extras, you still need to know basic details so that you know who and what you're talking to/interacting with.

I personally believe having a character sheet shows that you know what you are portraying as well as that you're going to put in the extra effort to display this character that you are playing. If you can't take a couple hours out of the day to make a well made character sheet, then you won't be taking time for my roleplay- which means, I don't have time for you either- ugly :gray[/i]
