Dear Challenge Participants, as recently announced, we experienced some internal delays, but submissions to the BraTPRO challenge finally opened a few days ago. You can find details about the submission process [here](https://www.synapse.org/Synapse:syn53752772/wiki/627310). If anything is unclear or you have any further questions, please don't hesitate to reach out to me. To compensate for the delays, the submission phase is extended until September 10th, with the possibility of a further extension if needed. We would be happy to have many of you present your solutions at this year's MICCAI challenge session. To help us prepare for the session, I would appreciate if you would let me know via mail (yannick.kirchhoff@dkfz-heidelberg.de) if you are interested to present your contribution. There will be small prices for everyone present. Best, Yannick
