This list is for the convenience of SharePoint users only. Access to each SharePoint site is restricted by membership. You will only be able to access the SharePoint sites in which you are a member. If you think you need access to a site but find you do not have it (a password dialog box will display when you do not), click Cancel on the dialog box and on the subsequent Request Access form, delineate who you are (complete name and e-mail address) and why you need access. Click Send Request. This will send a request to the Administrator of the site.
