A: Yes, most definitely. You can set your workspace domain to any url you want and change it later. What the URL value does is prevent someone else from copying the custom script we give you and using it to display your button on their website. It's more a precautionary feature than anything.

So if you go tier 3, you could use your 10 upgrades immediately and create workspaces with domain placeholders like example.com.

Hope this makes sense. - Pete
