Hi Scott,
While https://www.wikidata.org/wiki/Wikidata:List_generation
_input/Scenario_C_splitting might go a little bit in the right direction, I'm mainly interested in how I and a help page could clarify adding new lists at this point to Wikipedia and Wikidata.
I think this is an important topic. However, as far as I got this, how exactly lists are added/introduced to Wikipedia(s) depends on community opinion and RFCs. So even if someone would provide a tutorial how that would work, it would not be possible to act on that right now. Thus, it is not in focus for the feedback on scenarios.
I assume that User:Jens_Ohlig_(WMDE) and User:Lea_Lacroix_(WMDE) are working on tutorials in the near future, however, this is coming, but not worked on right now. What exists though already, are videos. Take a look at the recent https://www.wikidata.org/wiki/Wikidata:Status_updates/2016_ 09_03 (see the events section)
Hope that helps, Jan
