[guadec-list] Petra has quit

[Koen Martens <gmc sonologic nl>]

Hi list,

A quick note that Petra has quit on us for personal reasons, she was on
gathering sponsor materials and guarding our commitment to our sponsors.

I'm looking for a replacement for this important task from the existing
pool, but if anyone wants to step up to this, let me know!

Gr,

Koen
