I'll post this on the thread as others might be looking for the same sort of information.
All HTML pages are presented on your computer through the use of some interesting coding. But the coding is not a trade secret, nor is it hard to get your hands on what you need, even if you have no idea how to actually write the code yourself.
Your web browser is all you need to get the code.
On the page that you want to lift and have formatted exactly as it appeared at its source, place the mouse area somewhere over the page (doesn't matter where), and click the right button. One of the options on the pop up menu is "View Source." Click that and a notepad window (WordPad if the page is large and you are using Windows 95/98/Me [why?]) will open up. This is all of the HTML code that makes the page run.
Scroll through the document until you find something that looks like the text of the article - it is rarely at the beginning as there is a whole bunch of giberish looking stuff that is needed to set page frames, buttons, ads in some cases, and so on (stuff you don't want to carry along with your posting).
Once you find the article, you will need to identify whether there is any general formatting that goes along with it. Usually this is in the form of a "blockquote" or "heading" command, but it will in all cases immediately precede the text. (It will take a few tries at all of this to get a feel for what is article formatting and what goes in the other stuff that you didn't need - that's where "preview" helps.) Click and drag to highlight all of the text of the article (it helps to have noted what the last sentence of the article says, because there is often junk that comes after that point in the code - all of that is totally unnecessary).
After the text is highlighted, a simple right-click, copy, and then paste (use CTRL-V on your keyboard for the latter) into the posting window, and voila.
Legal issue--Be sure to give credit when doing this, as you have not created new work but have used someone elses.
No professionally made webpage will have a line of text that goes from one edge of the screen to the other. You don't have to be a reading expert (or reading teacher, like me) to figure out that it's vastly more difficult to read long line lengths than short ones. You can read much faster with much less effort if you're reading something that is not more than 4-5" from side to side.
When I post an article, I always place at least 3 < blockquote > commands at the beginning of the article. That narrows the column to about the right width.
