May I suggest that you be more specific about the topic. There are a lot of meetings in Wrightwood and if your goal is to get people to show up, it needs to be more specific and also posted on Facebook which is where a lot of folks get their information. Posting the agenda would be a smart idea as well so people don't have to search for it.
After reading the OP, I googled "wrightwood csd". The meeting agenda, board packet, and previous meeting info was all readily available on the home page when I tapped the first link.
If that is too large a feat for an individual to overcome, I wouldn't too much weight into that individuals input regarding community matters (should they actually show up to a meeting, which is not likely); I'd predict that any input from them should they show up to be obviously self-serving, and deserving of little to any time from the Board
Edit: posting meeting info on this site is a courtesy (I doubt Robert-roos requires forum/social media notification) and should be treated as such, imho.
