It's something that Joe and Bat are continuously working on. It is important to remember that they are only two people and have a big task at hand, outside of other responsibilities they may have off site. it may not be possible to have the score sender work the way we are used to in the past; the reCaptcha aspect of it remains very tricky. Our staff team are doing the best they can, but we don't know fully know for sure what is or is not possible with the wrench the reCaptchas throws in the equation.
Keep playing as usual when you can to keep up your personal momentum. The Altador Cup is not necessarily about getting the highest scores possible; it is about friendly competition between all of the different teams and lands, playing because you enjoy it and want to achieve a higher rank for prizes and fun.
And hey, what would you do if a score sender didn't exist, period, and was not a possibility to create one? You'd still have to play the "old school" way, anyways!
