I signup with dotster web hosting since few months ago, and hosted this dotster review site at dotster hosting plan. To login to dotster control panel, you have to go to dotster homepage, and click the my account link. Enter your dotster account name and password, and process with the login.
Dotster hosting is using their own control panel. And not using control panel like cpanel, h-sphere, or vdeck control panel. Screenshot below is taken form my dotster account, and this is what the dotster control panel look like. Use this as a dotster control panel demo.
