The best way is to not make those comments in the first place.
But people (like me) do make mistakes with "comments/replies". And that is why I had opened up this/my forum topic.
If you have specific ideas about what you want, please spell them out. Staff do pay attention to these threads, but they'd need more to go on.

Okay, while showering earlier, I had thought about what you said/replied. Here are my thoughts and I hope it helps improve the blogging community here at WordPress.com.

My main concern is the lack of control to moderate "comments/replies" made by WordPress.com users, who should be able to "preview" their "comments/replies" prior to submitting a "comment/reply" to weblog posts hosted on WordPress.com and/or WordPress.org.
And if WordPress.com users already submitted a "comment/reply" to weblog posts hosted on WordPress.com and WordPress.org and ALSO to WordPress.com forums but would like to "edit" their "comments/replies", I would like to suggest a time frame of no more than four hours before this "edit" feature cannot be modified, for example.
Also, I would like a "field" in place as a REASON for the "edit" to comments/replies made on posts and/or forums.
