There is a little "edit reason" box at the bottom that you can explain why you needed to edit your response.

_{Post edited by vid1900: fixed sentance structure for clarity}

I edit my responses a number of times after entering them (mostly to correct grammar).

I will enter a new line with the "edit:" callout and the additional content if I'm adding more information or if I'm changing what I typed in the original comment

edit: just like this

It's only really bad form if you make several douchey posts....and then after people start calling you out on your nonsense you run back and edit your posts to look like less of a twerp.

For the most part, editing your post is fine, even if it has been quoted.

...unless you are a gigantic tool.

To me, it's better than having a bunch of separate posts with one line in it.

I edit my posts all time time to fix wording or add a few sentences, but only if it's recent. I'll click post and then realize I was maybe too harsh, or that I could explain something more and I'll fix it. If it's right away I don't mark it as edited, though I'll do an edit: etc if I don't catch it within moments just to be clear.

dirty pool, old man. i like it!

Yup to all that.

I think the only real bad form is editing someone else's post and quoting it to make them say something different. Unless it's really funny.

I've spent fifteen plus years clarifying inside the body of a post before resubmitting anytime I edit something. I doubt that's going to stop any time soon.

edit - Like this.

Good form when appropriate. I recently edited a few posts because I inadvertently posted fals statements (which would make them rumors, I guess) that I thought was true. It was appropriate for me to correct the statements and take accountability.

Some fun stuff can be found here when posts are edited significantly after being quoted!

Or the other way around...................................

And that's generally fine. I do that too. Pinside does not have a preview button so posting, to me, is like preview. I will fix typos, add sentences etc.

I would suggest that editing is fine if it's recent and only until someone quotes your post. After that, an edit reason is absolutely mandatory if you ask me.

I almost edited my initial reaction post after someone bought the fire pin I was driving up to get. It was my initial knee jerk reaction but felt after emotions calmed down a bit harsh. I left it but said I didn't feel it was appropriate when I calmed down... it was the way I was feeling tho so left it.
