Happy Monday! I took some time to revise one of Flowbase's open-source projects and added Memberstack to it. I removed/renamed a few classes, updated the page copy, and added Memberstack links to some of the buttons.
Note: you could use this template with Memberstack's pre-built UI (the one you see in the template now) or you could link directly to your own custom signup form. Totally up to you.
If you have any questions, feel free to drop a comment below. Thanks!
