How to change space between two articles in TP front page ?

What are your frontpage settings? Are you using Frontpage blocks or are you using articles, or something else?

Also, make sure you do not have any extra returns (i.e. white space) at the end of the article. As hitting the enter key once or twice at the end of an article can add extra lines of space to it.

That top article should not have any more space at the bottom than the other articles have.
