Support request with team editing experiment project
Dear tech ambassadors, instead of spamming the Village Pump of each Wikipedia about my tiny project proposal for researching team editing (see here: https://meta.wikimedia.org/wiki/Grants:IdeaLab/Research_team_editing), I have decided to leave to your own discretion if the matter is relevant enough to inform a wider audience already. I would appreciate if you could appraise if the Wikipedia community you are more familiar with could have interest in testing group editing "on their own grounds" and with their own guidance. In a nutshell: it consists in editing pages as a group instead of as an individual. This social experiment might involve redefining some aspects of the workflow we are all used to, with the hope of creating a more friendly and collaborative environment since editing under a group umbrella creates less social exposure than traditional "individual editing". I send you this message also as a proof that the Inspire Campaign is already gearing up. As said I would appreciate of *you* just a comment on the talk page/endorsement of my project noting your general perception about the idea. Nothing else. Your contribution helps to shape the future! (which I hope it will be very bright, with colors, and Wikipedia everywhere) Regards from User:Micru on meta.
