This is the {{subst:canvassed}} template.

Usage change

This template should be subst:'d and takes two parameters, the second one being optional:

To specify a specific canvassed editor:

{{subst:canvassed|1=Username|2=(optional)link to diff (resembling https://simple.wikipedia.org/w/index.php?diff=prev&oldid=12345)}}

To specify the generic "editors", make |1= blank:

{{subst:canvassed|1=|2=(optional)link to diff (resembling https://simple.wikipedia.org/w/index.php?diff=prev&oldid=12345)}}
or:
{{subst:canvassed| |2=(optional)link to diff (resembling https://simple.wikipedia.org/w/index.php?diff=prev&oldid=12345)}}

This template supports up to 8 diffs (parameters |2= through |9=), mostly for the "editors" rather than particular username case (e.g. to identify notifications to select wikiprojects with a similar viewpoint but no particular stake in the matter, or a number of editors notified at their user talk pages):

{{subst:canvassed| |2=https://simple.wikipedia.org/w/index.php?diff=prev&oldid=12345 |3=https://simple.wikipedia.org/w/index.php?diff=prev&oldid=12345 |4=https://simple.wikipedia.org/w/index.php?diff=prev&oldid=12345}}
