Hello
As far as I can see, the only way of using SourceTree, is by creating a bitbucket / atlassian user. SourceTree uses that login to message home every time you start it.
Question 1: Can you add as many users as you want, if you only plan to use SourceTree with your own git repo?
Question 2: Can you use SourceTree when offline?
Question 3: Is it possible to buy SourceTree, to avoid having to create an user and to be able to use it offline? The company I am working for is looking for a good GIT client and doesn't mind paying for it.
