[Hotstorage-organizers] HotStorage'26 paper — non-student workshop registration requirement

Tue Aug 25 10:19:27 EDT 2026

Hi all,

It's exactly as Promod wrote. 

Regarding Guilherme's registration, we will make an exception and allow him to register at the student rate only. 
There was an error on our side in this particular case, and therefore we are willing to make an exception on this occasion. This should not happen again in the future.

Best regards,
Tomas
