[Support-lattice2022] Financial Support Christian Schneider

[Stephan Durr]

Dear Christian Schneider,

we are very happy to let you know that we can grant your request for a
reduced conference fee. In exchange we hope that you will volunteer to
help us with small services (e.g. carrying the microphones in plenary
sessions), with details to be specified while at the conference site.

Technically this will happen as follows. In a couple of days you shall
receive an Email by Heike Froembgen-Penkert from Bonn university. In this
Email you will find a voucher code with the help of which you will be
able to register for the conference at the price of 100 EUR. If you do not
receive this Email within 1 week, or if there is anything unclear about the
technical procedure, please do not hesitate to write back to us.

Please do NOT register to the conference now, since any registration and
payment cannot be undone. However, you can move forward with booking
flights and/or accommodation, hopefully avoiding future price hikes.
Note that we cannot provide support for travel and accommodation.

We look forward to seeing you at Lattice 2022 in Bonn.

Best regards on behalf of the LOC,
Stephan Durr, Stefan Krieg, and Akaki Rusetsky
