San Francisco Examiner: Services at a post office in San Francisco’s Tenderloin that is relied on by many homeless or low-income residents will be relocated effective Monday.  The P.O. Box and general delivery service at 101 Hyde St. will be moved to other locations ahead of the construction of an eight-story, mixed-use building that’s been proposed at the site, U.S. Post Office officials said.  General delivery mail will be provided at 391 Ellis St., and P.O. Boxes will be relocated to 1390 Market St. Customers will retain their current P.O. Box number, box size and zip code. Read more.
