Why should I avoid deleting my posts on Q&A forums?

Out of courtesy...

Deleted the poster name...

But message is still the same...

"Why did you delete your posting?

Answers to the good question you asked helps others greatly.

If you are going to delete your posts..

Then forget asking next time.

We will not waste our time replying to your question. As both Ben and I had taken our time and replied to you.

Thank you."
