The homepage and help panel features are both running in A/B tests with half of newcomers having each one -- but the two tests are independent. So right now, 25% of newcomers have both features, 50% have either one or the other, and 25% have neither.
We intend for the newcomer tasks work to use both the homepage and help panel platforms. Therefore, we need to align the treatment groups for the homepage and help panel features so that all newcomers in treatment groups who get one also have the other, and the control group gets neither.
Here's how we want to do it:
Retroactively turn on the help panel for all users who had the homepage. Then 50% of old users (starting in the homepage era) will have both features. Also, 25% of old users will have help panel and no homepage. Going forward, align the treatment groups so that all new accounts in a treatment group get both features. Users that have both features then get newcomer tasks.
