I have signed up for a free hosting today, 3 hours ago, but just a moment ago I was reading confirmation email, and... I've made a mistake while typing Desired Domain, I forgot to add ".com", so the Control Panel URL is wrong, and I can't register nameservers with my domain provider. Is it possible to add that ".com" to my submitted data, or should I re-register with correct data? I have used the same username and email as I use here on this forum. And yes, I have reviewed my submission carefully, but I missed that one. Also, I cannot login to a Control Panel, is this because I have to wait 24+ hours, or due to my mistake in sign-up data? Thank you!
