XP Bonus for Session Summaries

I've enjoyed writing up the session summaries each week, but I don't always include all the details that might be interesting to people. Mostly because I forget. So to get different perspectives, I'm encouraging my players to write summaries by offering an xp bonus based on their level. It needs to be posted in a public place, either on this blog or elsewhere on the internet, reasonably detailed, and before the next session. The awards are roughly based on 5% of the xp the fighter needs for the next level, and are as follows:

1   100
2   200
3   400
4   800
5   1500
6   3000
7   6000
8   12000
9   20000
10 25000
11 30000
12 35000
13 40000
