I received an invitation to collaborate but can’t sign up - LastPass related bug

We have a known bug that is related to using password manager applications such as LastPass, Passpack, etc. If you receive an invitation link to collaborate on a Librato account but are not able to create a new account, chances are you are hitting this bug. The password manager automatically fills in an email field that we use for a bot check, which results in a redirect back to the signup form without the collaborator token. To bypass this problem, please try disabling your password manager on the signup page.
