I'm going to play along here, but I'm not going to do your work for you. Go to www.xxxporntalk.com and look at that page. look at the black bar across the top of this page. Does that look effective to you? Why?

It's because the most prominent thing about it is the text "xxxporntalk" and then the modifying text accompanies it.

I suggest making "toplistxxx" the focus of the logo, in a pleasing way, then adding "sex forum(s)" as modifying information.

Edit: I and a half dozen other posters here could do this for you in about five minutes but I'm not interested.
