My external users (customers) would like a summary of new Ideas submitted each week to know if there is anything they may want to look further into or vote on.
I absolutely agree with this need. One customer new to using the Aha! Ideas tool said: "Daily Digest options have been available for over a decade on comment/community sites like this so we aren't talking about a wild innovation. "
Seeing string relationship with https://big.ideas.aha.io/ideas/A-I-8477... As I said there, we're receiving strong customer feedback that is frustrated by the limited nature of subscriptions in a portal. They'd like summary digest and ability to follow a specific product and filter to only get notified of new ideas.
