After purchasing the new account, you will receive access to a "WHM Accelerated" Control Panel. It is from here that you will be able to set up your sub accounts. I set up five different sub accounts. Each of these has their own cPanel log in, disk space quota, and bandwidth limit. I used the installation guides provided by HostGator to set up the various accounts. It was a bit of a pain to set up, but at the end I had cPanel accounts to give to each of my prospective webmasters.
The main reason that you would want to use HostGator to register your domain is that they are more reliable. When you register a domain the company that you use will place it on their DNS server, this is how people will find your site. If that server is not reliable nobody will be able to access your site. Most companies use two DNS servers, the primary one and a back up. HostGator on the other hand use six servers that are all located at different locations. The result is that your site will be much more reliable and people will be able to access your site whenever they want.
Awards are given each year for web hosting sites like Hostgator. They have won many awards and are practically a household name among web site owners. Their customer support and low priced hosting attracts business from all over the world.
Those 3 reasons are enough for anyone to choose a host and are the basics of what you would look for in a host. You could go use a host that doesn't have Live Chat Support and end up in all sorts of trouble especially if waiting hours website for a response.
You are going to receive just about the same exact feature from both hosts. They both offer the cPanel dashboard, with site builders such as Fantastico and Simple Scripts. Both support Ruby on Rails and PHP5. They offer unlimited bandwidth, unlimited e-mail accounts, unlimited storage, unlimited FTP accounts and much more. You can look through the compatibility documents of each host to make sure they will support your needs prior to buying a package.
Finish setting up your account (which is very easy...just follow HostGator's instructions) and then check your email for your confirmation email from HostGator. In this confirmation email, you will be given two nameservers: NS1 and NS2.
When you talk of customer support, this is the only company that solves your webserver problem within minutes. HostGator staffs are dedicated and are even ready to solve the problems in your website that does not fall under their area.
