can you have a Linode account w/o having an active server?
This is suppose to offer a small testing environment, fast and easy.
and I guess is cheaper that Linode to just keep it a little bit longer online...
You can have a Linode account without any active VPSes on your account. If you want to spin up a Linode for a day, you get charged a prorated amount for the day(s) that it is active on your account. Pretty reasonable IMO.
Just note that you need to have an active Linode on your account in order for any DNS records hosted with Linode to be served.
