As a poweruser you can view your research group by clicking on the button at the top of the page. You can also view the current members of your research group by clicking on the members button on the right hand side of your group. This will bring up a list of all members in your research group, as well as their roles and start & end dates. New members can be added by clicking the add member button, however in order to add a member to your group they must have a registered account. First choose the new group member from the list of currently registered users. Then choose their role and the start time. The end time should be left blank if the user is currently working in the group. Finally click on the add button and thats it, the user has been added to your group!
