Yes, but you need to be a Site Admin to create user groups.
To create a user group:
- Click Admin in the SourceForge toolbar.
- On the Site Administration page, click Groups.
- Under Groups, click the group to which you want to add the user.
- On the Edit Group page, click Add.
- Use the picker to move users into the group, and click OK.
- Click Return.
If you are not a Site Admin, contact your site administrator to create user groups.
