Argh! Fixing something else, I just noticed https://atbref.com was re-directing to the atbref10 baseline, not atbref11. Apologies to all. 
What I was adding is https://atbref.com/search.html. That short URL, short enough to remember, or bookmark will auto-redirect to the search page for current aTbRef so currently https://atbref.com/atbref11/search.html. I think the search feature seems stable and good enough that for most people it may be a better place to start than the home page.
Of course one more thing I have to remember to update when atbref11 eventually becomes atbref12.
