Your Grammar Points block made me look again, and it appears you started a sentence with a conjunction! The absolute worst offense, which no writer must commit, thou hast committed! =P

I just got here; what's this $20 contest?

Very nice! Three points to you, good sir. Entry fixed.

To quote another entry in my blog,

...my mother announced that [...] each week of summer break hereafter, a contest would be held. The theme and objective would be different each week, and the winner of each contest (either by popular vote or mother's choice) would receive $20. For those who don't know, I have a 10-year-old sister and a 13-year-old brother that will be competing with me (I'm 15 years old). The contests [usually] open and close Friday nights at 8 p.m.
