Can Blocs a) schedule content? For example, can I set a webpage to change its content on a weekly basis? Or is there a Bloc or a Bric that would allow me to do this?
b) password protect a single page without going full on membership site?
No, not out of the box. However @Jannis creator of Volt CMS has a password protector built in. I don’t know about scheduled events. I’m sure he’ll stop by and let you know soon.
