Kai Kreuzer (-1) Matthias,
Being an active blogger on random IoT/OS stuff and being „motivated to help“ is usually not sufficient to nominate somebody as a committer, see http://www.eclipse.org/projects/handbook/#elections-requirements:
A committer nomination should explain the candidate’s contributions to the project and thus why they should be elected as a Committer. Cite the issues they have fixed via patches; cite the community forum postings they have answered; cite the dev list design discussions to which they have contributed; etc. In all cases, provide urls to source material.
If you can provide such information, please file a new nomination for Charif.
If you have any concerns and want further clarification, please follow up on https://www.eclipse.org/lists/iot-pmc/msg04927.html. Thanks!
