The "blue link" is called the URL I suggest for easy posting that you use an Advanced Editor with HTML base. You will know this if you have a bunch of icons at the top of the page where you change fonts, colors, etc. There will be an icon that looks like a "chain link." If you have mouse over, you can find it by mousing over the icons until you find the one that says insert/edit link. Click on the whole link, not the broken link and you should be able to add your link there.
Let me make this a little easier. When you get to the point where you want to add your link.. lets say for instance.. http://www.DrMike.com.. highlight the link, like you are going to copy it, then click on the "chain link" icon. A pop up window will appear where you can type in your link; put a title on it; open it in a new window if you like. I hope this helps.
