If you go to a labkey page and dont have permission, you get a 'you dont have permission to perform this operation' page. It would be kinda useful if the page also had something like 'If you believe this is an error, click here to notify the site administrator'. This could be as simple as a mailto link the opened an email to the site admin email, possibly with some context in the body of the email.

On a similar vein, on the labkey login screen where you enter your password, a 'Click here to request an account' link would be nice. This could also be as simple as opening an email.
