There are several reasons why you might want to replace your school's default Home page with a new, or a temporary one.
A reason could be that your school is not ready yet, so you wish users to see an Under Construction or Pre-launch page since you are not ready to welcome your first users yet. Another reason to replace your school's Home page could be for a special event hence, you want to set up a temporary special landing page e.g for a Black Friday promotion or the launch of a new course.
Let's see how you can do this.
1. Go to Site Builder → Edit School Site, and navigate to your Pages Manager.
2. You will notice that there are different types of pages. Currently, your home page has the /pages/home slug.
3. Click on Clone Page.
4. Once the page is duplicated, click Site → Site Navigation, to navigate to your Site Navigation.
5. On the window that appears make sure to click Select a page and choose the page you wish from the drop-down menu. Once you are done, click Apply.
Set an existing page as a temporary Home/Landing page
If you do not wish to clone a page but choose one of your pages, navigate to Site Builder→ Navigation and follow the instructions in Step 5 to choose a temporary Landing page, from your already created pages.
Once you want to revert back to your previous Home page, follow the same process as shown above and choose the default home page in your Site Navigation.
Disable Sign in/up
There might be the case while building up your school and setting up a temporary page, you also don't wish users to be able to sign in/up yet in your school till the final product is ready, so they see for now only the "prelaunch" landing page you have created.
In case you decide to disable sign-in/up you can do so by Managing your Login/Sign-up Settings and disabling sign-in/up.
If for restrictive access reasons you decide to remove the top bar of your school hence the sign-in/up button on it, you will have to use the below strings at the end of your school's URL in order to trigger manually the sign in or sign up form:
So e.g you will need to type this link www.yourschool.com/?msg=not-logged-in (replace "yourschool" with the name of your school), in case you have a custom domain, in order to log in to your school but do not have a public Sign in/up button in your topbar or you have disabled completely your school's topbar till your launch. Accordingly, you need to follow this link www.yourschool.com/?msg=signup to sign up.
