Yep, I've been away for awhile.

Options are Bootstrap 4, Foundation, or Materialize.

Which one affords me all the "new stuff" AND won't break my site?

Oh yeah, and I can't find a search input box in the forums. So there's probably already an answer out there for me, right? Using Firefox and no search box. Thanks in advance!

Edit: Okay, so THERE's the search button; on the post reading page, not the topic list page.

Nevermind! I found a good thread on this, and I think I'll choose Materialize and see what happens. "Save As" is my friend, of course!

Whichever you choose there is a lot of stuff that will need sorting out especially from 1.5
