@PraveshParekh yes, PS is sloppy; it rescues your signal-to-noise by making it less clear what the purpose of your email was as a PS comment may be an entirely different subject matter (and perhaps should be a different email) or an aside, or something you thought of that needs an urgent response.

A postscript is a passage at the end of a letter, following the signature. It only makes sense in the context of a letter composed by hand or on a typewriter, to accommodate an afterthought when you have already finished your letter, and don't want to retype or rewrite the whole thing again.

@Neil Fein, I disagree. It can be used to deliver a punch line, that could even change the interpretation of what comes before (a taste matter).

我是从2016开始接触ps软件的，当时最开始下载的PS CS6版本，到现在已经换上了2024的版本，作为设计师，无论学习还是工作都中建议用新版，因为每年都在更新，功能也越来越多，使用自然也越来越高效。关键也要学会与时俱进。

那么到底哪个版本最好用呢？这是很多ps新手比较关心的问题。 我从06年开始接触ps，到现在也有十多年了。我说说自己使用PS的心得感受，仅供参考。 从06年到现在，我经历了ps的10来个版本的更新。

I will make specific mention, however (as I did there), of Karen Hertzberg's blog post "What PS Means and How to Use It Correctly in Your Email". It expands on the idea of using postscripts stylistically. But all of that aside, you can literally do whatever …

Photoshop 2024都出来了，2023还没用过，目前在用cs6，有必要用最新版本的ps吗？
