Steve (sfish): I see you made a duplicate posting (it happens) along with another posting containing a typo in this topic. Both of these are easily correctable.
While you can edit a duplicate to remove the text, there is an option to delete the duplicate posting all together.
Additionally you can re-open your original posting, the one with the typo, to correct any error.
How do I do this you ask? Easy. At the top of any posting is a series of icons. If you were the author of the posting, there are additional icons.
The additional icons are the third one (paper with a pen) and the last (sixth) one, the image of a piece of paper with a trash can. Clicking on the paper with pen icon opens an "Edit" session of the posting so you can change, modify, or alter the contents and then re-post it in its new improved form. Clicking on the paper with trash can icon will delete that posting.
If you have any questions, feel free to PM or e-mail me.
