It's an acronym, right? Aren't there already other topics about plural with acronyms? I can't seem to find any but I remember I saw some :| – Alenanno May 3 '11 at 7:08
There are many meaning of POC, I think that you have to specify which one you are using in order for the question to get a specific answer. en.wikipedia.org/wiki/POC – Guffa May 3 '11 at 7:51
@Guffa: he linked to the correct one, proof of concept – nico May 3 '11 at 7:55
@nico: He did? Yes, you are right, when I know that there might be a link, it's possible to hover around on the text to find it... Who picked the color for the links? :P – Guffa May 3 '11 at 8:35

POCs is ok.

To pluralise an abbreviation (or number) just add an "s" to the end.

Isn't it normal to add apostrophe's to all the word's you pluralize, even when they're not acronym's? – Andrew Grimm May 3 '11 at 8:06
@Andrew Grimm: No. – Guffa May 3 '11 at 8:36
@AndrewGrimm: Nor in apostrophe's, word's or acronym's for that matter. – Kris Jan 4 '12 at 9:03
