No thanks. I hate it when people see a "read" indicator then act stupid if you do not respond right away. Going on about being "left on read" etc.. Some people are busy and have a life. This "read" indicator only makes life more annoying for us. I think the "read" feature should be optional.
"Show sender when you have read their messages" type of box-check deal. I would not check this box, but if you want to you should have the option.
