Highlighted Blue & underlined?

What is that all about, anyway, with words [not selected by me] highlighted in blue & double underlined?

They are links to ads, other sites, etc. They showed up a couple months ago- i complained about how annoying they were then, and they disappeared for a while, now they seem to have re-appeared. Not sure why.....

Amanda is right. Aaron aware of the first occurance; he'll be alerted to this. Please be aware he is working some long hours, over 1 hour from home....
