Adding a Text Box
For things like the affiliate disclaimer or other information that needs to be highlited, a text box works very well. It can also break up the content of you article or define a chart or graph. Although there are downloadable programs to insert text boxes and other specially formatted things into you content. A snipping tool, whichever one you use, is easiest.
Prepare you text box, graph or chart using your word processing program. Capture your work with your snipping tool. Paste the captured box into your article where appropriate.
The formatting used by the word processing program is locked when captured by the snipping tool. The text box can be manipulated as you would any other image before placing it into the article and after placing it as well. Using this option, a link can also be added.
I hope this makes it a bit easier for you to keep on fishin'!
