Dear all (and Esmi if you're there)
I have been seeking a definitive 'what happens, is it worth it?' answer regarding changing my default, two-year vintage permalinks in default format into something ending with the post name, that is, prettier.
After a trail of missing or defunct plugins and opposing views as to the effects (404s, dead bookmarks across the membership etc) and the worthwhileness (?) of changing, may I request, at your discretion, a short, sharp 'This is what you do, dummy, and it is/isn't worth it so do/don't bother'
Ideal - smooth transition from /?page_id=755 to /fluffy-kittens-with-semi-automatics
Thanks in advance - always appreciated
