This has provoked much excitement in London! In the words of one of our staff, 
"This is absolutely excellent. What we need to do is make sure all volunteer event leads are aware of this (because in my experience, they are the ones pointing people towards account creation on the day), and that there is a standard format for naming event campaigns (for example; if we called one 'editathon' then we could be conflating different event metrics if they were both editathons)"

I thought I'd share these with this list - it's an excellent project, but we need to plan how to deal with the naming format :-)

Hi everyone, 

Last week the Editor Engagement Experiments team deployed a new extension to all wikis, Extension:Campaigns ( 

The campaigns extension does one thing: if you add "campaign=example" to a link pointing at the account creation form, it logs the campaign name at the time of signup. 

This capability has been around a long time in some form or another, but we disabled it so we could get to work on our redesign of account creation and login. Now that's it's finished, we wanted to make it available again. 

There's more in the documentation I linked to above, but the general point is that this gives us a low cost, minimally invasive way to figure out how many people are coming to sign up via a particular avenue. 

Among our first test cases, my team would really like to know if significant numbers of people are signing up via the links English Wikipedia puts in system messages directed at those viewing semi-protected pages and anonymous editors. I've put up a proposal about this on-wiki at

If you have any questions about how campaigns work and how they might be applied elsewhere, please speak up. :)
