Right click on the original page, and select "View Source". Find the html source for the part you want to post, and copy and paste into your FreeRepublic posting. Preview to be sure it made it across in usable fashion.
If you use Firefox, instead of Internet Explorer, you can highlight a portion of the original document, and then the right click menu will have a "View Selection Source" which just shows the html for the portion you highlighted, instead of the entire page's html source. For complex web pages such as that blog, it is worth downloading Firefox just to get that feature, and save having to read through the html of a large web page to find the chunk you need.
About the only hand work I usually have to do is to ensure that any images <img src=...> have their src URL converted to a full path, instead of what is common - a URL relative to that of the html page embedding them. The above post had no images of importance, so that didn't apply here.
I will take your word on this ;^) . . .really thought I would have to re-format the whole thing; appreciate the steps and will practice - tomorrow.
Have been wanting to learn more html; and just started bookmarking some sites. (Needless to say. . .I am now more motivated) - just changed recently from Dell to I Mac; so have quite a bit of learning ahead. . .That said, I miss my 'Free Cell'. Microsoft has the best version; nothing else compares. . but I digress (!)
