That is my concern. If I build a book case from IKEA or something and wind up with an extra nail, no biggie. If I wind up with something extra here might be a biggie. I have watched the LIM Video quite a few times but it is not working now since the site updated a few days back, or at least it was not working earlier, I'll check it again of course. I'll try the GPONA thing too though, that sounds very helpful. Thanks to everybody that threw out a suggestion.
