I've recently joined our PTA. It's a super group of hardworking people but sometimes I feel their communication with other parents - ie those who don't attend the meetings but are very interested in the school - could be improved. Their response to this is "if people care, they will come to the meetings or talk to us on the playgroud" and I feel that is a bit narrow - not everyone can fit PTA meetings into their lives, and not everyone has the leisure to prepare what they want to say on a topic, walk around the school at pick-up to track down committee members, see if they're free and have the chat.
I have had an idea that we could have an internet forum (not unlike this one or like a Yahoo! interest group) for our parents. Decisions would still be taken at the meetings but those parents who are at work in offices could check in during the day to see what was happening at school. I feel this could be particularly valuable for divorced non-resident parents who still want to know what's up with their child. We could circulate PTA letters by posts on the forum rather than wasting paper sending them out to all parents. PTA letters wouldn't get "lost" any more because they'd be captured on the forum.
There would be the usual etiquette issues plus additional security considerations. I think people would have to use their real names, and would also have to apply in writing to be "invited" on to the forum. It could be fully moderated - at least at first - just in case someone wanted to send a "gripe" round the whole school.
Areas where I feel it could be invaluable are, for instance, our "eco-schools" project. I'm on the committee for this and I already copy in a few interested friends to the minutes - but there could be dozens more who would like to be updated - without 270 sheets of non-recycled paper being used each time!
