Hello, a quick question

Lets say we have a catagory called "TestCatagory" in my "Teststore". When you go to that catagory (frontend) it builds the following screen:
Teststore :: TestCatagory
TestCatagory // <---- This is what i want removed
|--------------------------------------------
| PRODUCTS Sort by: blabla
|--------------------------------------------
|
|
|
Basically I see no point in having the top navigation line (which is good) and then have the current catagory name again below it just above the product table.... As the current catagory can be read from the top nav line anway and it looks weird having the same name double all the time... (and wastes space).
How can I remove this line ? Which .tlp file do I need to edit ?
Thanks!
