How to edit group on the SharePoint quicklaunch in WSS 3.0 (and MOSS 2007)?

It is always a good idea to lock down SharePoint sites such that users do not see more information than they need to. At the organization where I work, we have a plethora of SharePoint groups. With any new website that gets created, a user with full rights gets to see a list of all the groups by going to "Site Actions / Site Settings / Advanced Permissions". There is always the danger that a user can inadvertently delete or add a user to the wrong group. One simple solution is to remove unneeded groups from the quicklaunch. Here's what you can do:

• Click on Site Actions / Site Settings / Advanced Permissions
• Click on any group on the quicklaunch under "Groups"
• Click on Settings / Edit Group Quick Launch
• On the "Edit Group Quick Launch" page, highlight any group and hit the delete key on your keyboard
