I think it depends on what accent you're talking about, Anna. I've always pronounced folks/FOLCs with an "l" sound in them.
I don't think I ever said it spelled-out, though I know some people who did -- I liked the play on words. We're not just any old folks, we're
FOLCs! <g> Plus I had a case of nickname-envy -- the X-File fans in the forum next door called themselves X-Philes, which I thought was brilliant.
I tended to pronounce the other acronyms as words, too, come to think of it -- "Home is Where the Hurt Is" (HiWtHi) was pronounced "Hiawatha" and "We Have a Lot to Talk About" (WHALTTA) was "walt-ah."
This can go too far, of course. I'm embarrassed to admit that sometimes I have, in verbal conversation, actually pronounced "lol"
