Thanks Tom, I guess I wasn't clear when i wrote "can't get rid", I did try removing them in Eagle but couldn't select the text in anyway.
However I managed to go around the problem, when I saved the .brd file it was converted to Eagle XML format and then I just removed the license text in a text editor.
Problem solved.
On OSH Park: yeah it's not the cheapest, I used it mostly for the .brd preview to make sure everything looks fine. Seeed seems to be even cheaper than DityPCBs.
I wanted to make my own Bus Blaster v1 (v1 because it seems to be the easiest and cheapest to make) and I have a question about the PCB file.
I got the .brd file from here but when I open it in Eagle there are two layers: _tsilk and _bsilk that contain information about a license and they make submitting the file to OSH Park impossible because they make the board larger then it needs to be (see image below). I can't seem to get rid of the text and/or layers.
Does this mean that printing your own PCB is not allowed? I thought it was open hardware.
