The quick and dirty way of using Word-Art for logos:
1)create desired image on Word
2)magnify/zoom to largest screen size to maximize logo view
3)use "PrtScr" (print screen button on keyboard)to copy page
4)paste into Paint
5)trim excess, leaving just logo
6)use "save as" to save resulting logo as a Jpeg
7)Add to site using editor in for site_name in concrete dashboard

obviously, many different ways to do this depending on your software... remember not to get carried away with this as images do not help your sites SEO when text should be used instead

I would like to thank you both for your suggestions. Unfortunately, I was unable to get either to work. My global scrapbook does not contain "My_Site_Name" so I created a content block and named it "My_Site_Name". Pasting word art into the content block did not work. It erased the name of my site from the website, leaving the top part of my home page blank. I also had the problem that Concrete5's file manager saved the jpeg as blank. I was able to paste the word art into Paint. However, Paint froze (a problem acknowledged by microsoft.com website). So, what do you think I should try now? Thanks a bunch!

I am also a newbee but I can recommend you a way to do that using powerpoint.
- First, type what you want using wordart in a slide.
- Then, select the text box, right click on your mouse and chose "Save as a picture" (you can save it in .png, .jpeg, .gif...)
- add this picture to the header (add block -> add image or content) and that's it!
Using this method you can insert everything you can create with powerpoint to your site.
