Exactly.

I think the 3 things are all different.
The PM "submit" button is the "slightest" action of all. Once you "submit" the PM, if you change your mind within minutes and decide to retract it, chances are it is still in the Outbox and you can edit/delete that PM and your recipient won't be able to see it at all. (However he/she might receive a email notification in his/her inbox letting her know that "you got a PM" but will never get to know the content unless you show him/her again.)
The "post to forum" is the next level up. Once you "submit" a public post, within seconds people browsing in the forum can see it. However, you can edit it any time to prevent any more viewers should you find the need to do so. And if you do so before others post a new message below yours, there won't be an "edited" mark at the bottom of your post to show how many times you have edited it, and you can also delete the whole post should you want.
The "send" button in email is the "strongest" move. Once your press it and the email is sent there is nothing you can do to retract it. Whatever written is delivered straight to your recipient's email inbox (barring any unforeseen situations such as servers being down or mistyping email addresses).
So my suggestion is, before you press the "submit" or "send" button, always use the "preview" button first (if available) and always think not only
twice, but
thrice before you actually submit/send it out to avoid any regret.
