Firstly, thank you everyone for your reply :)
Secondly,
Agathe & Alex: I followed your advice and found people I can talk to during the conference. For Wednesday Day trip I choose Plan A (Hiking Along the Coast). I see we will be 54 people to walk outside, I will use this opportunity to meet new people.
Alex I don't know which option you chose, but if it's Plan A too, I could help you to translate in French.
Jonas: I would like to meet you, but I don't really know *when* and *where*. Tomorrow (and every morning of this week), I will be on Centre-Vie at 7:30.
And I don't register for breakfast, I will see if I can pay on site.
Jonathan: As sayed Jonas, I will be looking for a closed circle and if I find free space at your table I will ask if I can seat with you.
Finally, I think this would be great too if will not be the only newcomer to meet the Debconf veterans?
See you all later :-D!
