I wanted to take the time to write a good review because one of the postal carriers took her time to help me out today. My uncle is coming in from out of country and didn't let us know he had mail coming. When our carrier asked my GF if this was our mail she said "no". I got home and tracked down a carrier on the st. I wish I had asked her last name but her first is Jill. She took out her cell phone called the other carrier, told him he could drop off my mail in her drop box and she would bring it to me after her route. I didnt realize how uncommon it is for people in everyday to go out of their way to help you until Jill offered. Thank you Jill


does anyone know if Ft Point will be reachable by car tonite for the thousands of people filing tax returns?


Good evening.
I represent the Royal Mail Choir. We are a group of mail-men and women formed into a choir for a BBC television series. Currently we are promoting a download recorded for an English cancer charity.Following to-days senseless bombing of the marathon we have suspended our Facebook page from promoting the download as a mark of respect for the fundraisers running the marathon and their supporters. I have tried to get in touch with the mayors office but I'd imagine things are pretty chaotic right now.If you wish to read messages of support from one postal service, and one country to another, please visit our page by searching Royal Mail Choir.Thank you and stay safe.
