Should I contact YC to update the progress after application?

Hi everybody~ Thx for viewing this.

Our team applied YC W2014 when we just started the project from the ground. In the past 6 days, we've made tremendous progress, i.e, nailing down more users, identifying another competitor, and almost seeing the first transaction. I know the first transaction doesn't necessarily mean there is a second and third till a millionth, but it is not zero anymore. Do you think we should try to update the application content by reaching out to somebody in YC? Thx a lot! If you think this is a silly question, let me know and plz tell me why, thx a lot again!
