This is a major bug in your product and it literally stopped our team to switch from git to plastic scm. I was trying out your product for the first time and after creating a project I invited my colleague to work together with me and she was not able to join my server. She was also checking out plastic scm and she did not join organization but instead created one. Later she was not able to join my organizaton even after several attempts. She tried to logout but she couldn't because that feature was not present in the GUI. She tried uninstalling nd reinstalling but still she was logged in. Finally she lost hope. You must definitely add an feature to logout and login from the windows application and also fix the joining organization after skipping it in login page.
