I just moved from 3 rep to 13 and received several notification of new privileges I earned. Among them was listed the ability to vote up and flag posts. When I checked those the FAQ said I need 15 rep and to verify this I tried to upvote an answer and wasn't permitted to.
Obviously this isn't an issue that is mission critical but I do think there is a mistake in design somewhere. Perhaps these privileges used to activate at 10 rep and the notifications still occur then as well.
