Hi Vladi, welcome to the forum. What you’re looking for is possible with Webflow and a couple of integrations. While Webflow doesn’t currently offer these features natively (no word on comments, and memberships are still invite-only in beta), you could integrate with a service like Memberstack to handle log-ins, and Zapier to take your comment / review form submissions, and add them back into your Webflow CMS (database) and automatically display on the website. Would be fairly seamless once it’s all set up.
