"One evening last week I was checking out the home page and saw that the blue block in the middle showing the What You Can Do was gone, and what appeared was an announcement for TGU. I thought it looked great, and when I checked the main page on the following day, the page looked like it usually does. Is it not possible to remove the blue block from the home page?"
Yes, it is possible to remove that blue block that sometimes appears on the home page, and I recommend you do so. Just click on the little 'x' in the upper right hand corner of the blue block. The block will disappear and you'll see the actual content that we have on the main page.
Heather, it is a featured discussion, but it's a reply to an older post, so you have to click on "View All" to see it in the Featured Discussions List. Perhaps we should make a new post, so it sits on top.
Thanks for all of your help you are giving to people trying to navigate this site!
