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.

These two campaigns have been enabled for a little over two days now. For the curious, I've gone ahead and shared preliminary results at https://meta.wikimedia.org/wiki/Research:Account_creation_campaigns/Anonymous_editors

Obvious caveat here is that a week's worth of data would be most reliable, since it accounts for normal behavioral changes in a working week. But I don't expect there to be a huge change in the proportions overall.
