I can never find anything on this. Heck, I dont even know what it is called. Check this out, http://www.entrepreneur.com/article/0,4621,322329,00.html
On the mousover on certain words theres comes a window with a brief explanation, and a link in it. What is this? What is called? I know its something dynamic, but it is boggling my mind to know what the exact name is for something like this.
Thank you all
There are other topics on the forum that explain in more detail how to do this, just do a search and something should come up.
