A real sign-up page, and a Get started button on the homepage

Sign up now has its own page: your name and email first, then your school and lab, then a free 2-week trial - no card needed. The homepage has a Get started button, and the sign-in page has a real Sign up button instead of a line of text about asking your admin for an invite. Pricing still compares plans (Free trial, Team at $99/month for up to 5 people, and Enterprise), and Enterprise has its own contact form that emails the team directly.
