WMF's Community Tech team is starting to work on a Cross-wiki watchlist,
one of the top 10 wishes in the Community Wishlist Survey that we conducted
at the end of last year. 
We're running a survey on how people use their watchlists, to help inform
our work. If you've got a minute and want to share your thoughts, here's
the survey link:
The survey's hosted on a third-party service. We'll be running the survey
for about a week, and once it's closed, we'll publish aggregated results on
Meta. Feel free to pass the link on, if you'd like to.
Let me know if you have any questions. Thanks!
Product Manager, WMF Community Tech
