Addresses don't show on the network until coins are sent to them.
So if that is your Devtome address but you have not received coin there yet it makes sense that the network was not seen it yet.
Though usually Unthinkingbit does a test send to make sure you listed the right address..

that address is my devcoin wallet on my laptop, i have had loads sent to it and sent just as much back out all over the place yet i see no records of it even being in the system .
Shows up fine for me. Shows only one coin was ever sent though.
