Does this website have a list of caregivers profiles we can read about them and then message them? Or is it just a forum?

Care.com does this. This site doesn’t. In fact you can’t directly promote caregiving services in the forum.

This is not an employment forum, it's crowd-sourcing answers from (mostly) private family caregivers to other such caregivers, plus education and support.

Just a forum check care.com or put a ad on Nextdoor.com
