In order to stay connected with the community, I suggest a Slack group and a LinkedIn group. These are the social media for business networking.

In Slack you can create different working groups on topics. The younger generation and startup people do all use Slack and LinkedIn In LinkedIn you can reach new possible members.

I also recommend to encourage the community to post in the LinkedIn group or in Slack what they are currently looking for or how they can help other members with their skills.
