So why are some people using full sheets and others are just listing a quarter of their attributes and such?
When I talked to Imogen, I got the sense that she doesn't want people posting their entire character sheets, just the stuff that's obvious at a glance, like Strength, Charisma, Appearance, and the things that can very easily be found out, like social merits and flaws, Clan and Status.
If you post the entire sheet and don't post the obvious stuff separately, people have to read over your sheet to find out such pertinent info. It then forces people to read over all the stuff and then have to ignore it. Rather than getting the chance just to find out IC what your character knows, the player is given the more dubious task of remembering both what they know and what they don't know, and can make coming up with theories rather difficult.
I've also been in games where people posted their entire sheet, then called foul when someone knew something about their character. In such a political game, this required the players to carry around heaps of data about what their characters knew, when they learned it, and so on, and it can easily turn into a nightmare for everyone involved.
Having read over the intro she posted, I may be wrong on this, and I've edited my post to match. However, I recommend having things set up so that only Imogen can see the entirety of your character sheet.
