We've launched a page on UserVoice. Head over there to vote on what carriers we should support next, or to make other suggestions for us. Perhaps you have an opinion on what the official sandwich spread of Packagetrackr.com should be. Hooray! One less thing we have to decide at lunchtime.
Whatever you think about the site, you can still contact us via the feedback form, (We love all the feedback! Keep it coming!) but in terms of prioritization, we think it's best to look at what you all are voting for the most.
Happy
