We use the information collected by the server provider (ISP) for efficient management of the site and this does not include any personally identifiable information. Common ways that information is collected include:

Server Logs.

The raw Web server logs record the following information, which we aggregate into monthly usage reports for site management:

• URL from which file request was received.
• date and time stamp.
• URL requested.
• file sent.

Cookies.

A Web cookie is text information that a Web page can instruct your browser to write to your browser's cookie file. Many Web sites use cookies to track usage patterns on their site on a page by page basis. We are not using cookies.

Monthly reports are run to help manage the Web site, primarily to confirm usage patterns, identify trends, and spot anomalies. Password access is required because it is very easy for those unfamiliar with the terminology and nature of server operations to misinterpret the results.
