Email Capture - start in new browser tab
The Email Capture tab in the Club portal isn't really a tab, it is just a link to separate tool. If you select the tab you are taken to the separate login / tool. Once you are in the tool there is no way to return to the Club portal except by using the back button, this isn't good design.
To help avoid this issue, open the email capture tool in a new browser window so that the Club portal is still available.
