The community is being defined in terms of
'people', rather than

'crat on English Wikiquote had ~hundred accounts with more than five
edits (Kalki).
There are also another ~75000 IP accounts generating at least 5 edits
per month. It would be even harder than the username case to figure
out how many unique people this represents. However, it would still
seem likely that there is a non-trivial fraction of the contributor
community who only edit anonymously.
