The Showcase is self-serve by design, but occasionally things go sideways. Here's who to contact.
Can't log in, or your invitation has expired? Reach out to the person who shared the Showcase link with you. They can get you a new invitation. Their email address is also listed at the bottom of the invitation email you received.
Can't find content you expected to see? Ask whoever sent you the link — they'll know whether the content has been published yet or which team's collection you should be looking at.
Something else seems broken? If the issue is with a specific item, leave a comment or reach out to the author directly — their contact is in the Property table. If it's a bigger problem, reach out to your organization's admin you can find at the bottom of each page.
