CD4-Chicago kicks off with this month's theme: Poz Box, like mailbox with a twist since the person your sending a message to just happens to be HIV positive or Pos friendly. Interact with other HIV Positive/Pos Friendly people by sending a flirt, phone number, message or even ask someone out on a date. Flirting with other HIV Positive/Pos Friendly people has never been easier. Free BBQ and $2 domestic and $3 import beers.
