including a link as evidence when trying to submit an update

I was disappointed to find the choreographers and reference dancers uncredited for the BBC's "The Supporting Act" http://www.imdb.com/title/tt7743592/fullcredits?ref_=tt_ql_dt_1 and went to some lengths to search for them (through all the many news pages ignoring their contribution) and then come back to IMDb to add them but was disappointed not to have a chance to give the staff here a reference link to check. Eg https://lectureinprogress.com/journal/bbc-blinkink

I also had to add a new category of "reference dancer" to go with "reference actor" (which presumably applies to people with more traditional acting roles or who perform in other ways, bodily or facially, for CGI or stop-motion films).
