ok so I take writing to HoS on myself if nobody minds? I think it will be impolite not to invite Tilo and Anne, and the band...
I'm sure nobody would object to you writing to HoS, as for me I was sure it would be you who would be doing it, anyway, so

And yes, indeed, it would be really impolite on our part not to invite them to our party! The only thing that concerns me, though, is that there is not much time in stock, but I hope it will work out, somehow.
Arkana, practically I'm in the same boat as you, because my classes were moved from last Saturday to next Saturday due to holidays, but we'll survive, in this I trust
