Hi, Since I haven’t gotten any reply and the paper seems to be still online, I am resending this message. We are planning to submit a revised version of this paper to a journal next week and it is absolutely necessary to remove the full version from the conference web site. Could you please remove it and just send a short confirmation. Thank you and see you in Druid22. Regards, Kimmo From: Karhu Kimmo <kimmo.karhu@aalto.fi> Date: Monday, 17.
