Ask HN: Have you used Senior Planet (classes, tech hotline, etc.)?

https://seniorplanet.org/ This is a non-profit organization, now running in cooperationn with AARP, that offers a collection of services - tech classes, videos, tech support hotline, etc. - for helping older folks use technology. It sounds like a great idea to me. I found out about it because I was thinking again of trying to start a similar business, and just noticed that these folks are now 'for real' -- they're going nationwide, etc. They've been mentioned before but I didn't see much in the way of comments: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=%22senior%20planet%22&sort=byDate&type=story
