Good news! Marketo Community has listened to your request, and we have enhanced our search functionality to include the ability to find people by their profile name! We hope this will help you connect with other Marketo customers and enhance your ability to network, innovate, and collaborate with other marketers like yourself.
Elliott, I know you, Caleb, and now Itay have requested the ability to search for just your discussions and ideas and we are working on updating the search fields that are there now to make them more specific to your content vs. others responses to your content. I'll keep you posted on progress!
