The primary reason I changed the help web site was to display the support form that you had to close to read this. The most common reason people visit this page is to submit a help ticket so I want to make that as easy as possible.
The things people do most are now the easiest to get to. I can also feature useful information from the support site that is hard to find, like maps and phone numbers.
The most common reason people come to the help site is to create a ticket, so that is on the front page.
The old system did not have a very flexible front page. This new front page design gives me more freedom to present information.
