That sounds good.  :-)  I think it'll be easier just to note xp on individual character sheets, and clear the xp tables every month or so, rather than trying to keep track of how much total xp everyone has.  It's much easier for you guys to think in terms of xp as points you spend, rather than an advancing total that provides benefits as the number gets higher though.<br/><br/>(I'm-a stretching the OGL to the breaking point, I thinks!)
