To make a word click able. Highlight the word you want to use in your message.Than go copy the blog address you want to use. Than on top to the left there's a green icon looks kinda like a frog to me, click on that a bar will pop up & you have to allow temporary pop ups. So allow them & click on the frog again & a box will pop up with http:// in it. Get rid of the http:// & paste the blog address you have copied. Click OK & your done! If your using the new blogger it says Link instead of the frog. Hope that helps!
