Hi John! I take your point. OK, let me break this into two parts.

Strategy 1. WMF needs to know (as much as possible) which editors are
female/male. It is pointless having a goal in relation to female
participation while we neither know what it currently is and whether or not
anything we do causes it to change or achieve the designed target. Right now
there are a lot of "ungendered" users on Wikipedia, who make it hard to know
what is actually going on.

So, having a campaign and or inviting new users to provide their gender
would be a Good Thing for measurement.

Just FYI, where is the user's gender revealed? I must say that, other than
consulting my own preferences, I have never noticed where my gender or
anyone else's is revealed, although I know everyone says it is ... somewhere
