Lets say I have a website in a private repo in Bitbucket with the Free for 5 users account, with Bug Tracking setup.
And I have a group fo 10 testers for my website.
For all 10 of those testers to use the Bug Tracking in Bitbucket, do they each need a bitbucket account AND do they all count as contributers? Therefore requiring me to upgrade the account to one that will support 11 users?
