I was looking at the Editorial area at the PI's website and discovered they have the audio from their editorial board interviews with candidates in Districts 2 and 6 (I don't know if the other districts are upcoming). I haven't had time to listen to them but I just wanted to pass them along in case you don't get to any of the pre-primary forums.
Also, August 7th is Neighborhood Block party night. If any of you live in neighborhoods that participate, you might consider it a good time to talk with neighbors about the upcoming primary (many people might not realize it's happening). I find that many people welcome information on school board candidates because they either don't have kids in the district or don't keep up. (I'm like this on port commissioner and judges; I never quite know who to vote for beyond what's in the newspaper.)
