My mistake, I'm dealing with many names and nicknames and I'm promoting the Summit through many channels.
Edit your maemo.org profile providing all the relevant information about you in the Maemo context. This will help us knowing/remembering who are you and what are you doing here. When registering, explain in your sponsorship request how can you contribute to the success of the Summit: run a session, get a responsibility in the organization, develop a demo to showcase... up to you. We just want to avoid sponsoring passive participants, no matter how much active they have been in the past. This sponsorship is not a prize for past contributions.
