Can I edit the subject line also?

I am sure if it can be done at all.

Just asking, thanks!

There's a time limit, if you reconsider or catch an error you want to correct in a post. Look for the "Edit" button on the bottom line. You have a few hours before it expires. You can retract a whole post, and if it's of your origination the title goes with it.

The expiration of the "Edit" feature permits corrections while preventing abuses.

Thanks, Jeff.
