Alternate accounts are allowed in Glitch as long as you comply with the official Terms of Service. The Gregarious Grocer app only supports a single active account BUT if you’ve got an alternate, you can now switch between your main and secondary accounts.
Make sure you are logged in to your secondary Glitch account, then click on the Logout link (located in the footer) in the GG app. You will be prompted to authorise the app again and once that’s done, you will be switched fully to this new account.
Sell-a-bot rules setup under your main account will be not lost. If you want to switch back, simply repeat the logout process and make sure that you authorise the app again with your main account.
