I did something before i dont remeber what it was. but i know it put a space between forums and moved the header under the catagory strips.
The error im having now is there is one at the top and bottom. how do i remove the top one?
What template will it be in and what should i be looking to delete?

Thanks

Let me know if you need more info or if i've said stuff wrong, Im new at this.:)
