I have been using it for a long time now, I find it really useful, much easier than the terminal based version there is on all unixes and whose name I have now forgotten, since you are not using that kind of gadget everyday, I remember I had to read once again the manual for the text based version while this GUI is so easy you do as you feel and it's the right thing to do. I had to reinstall it though when I upgraded to Leopard, just erased it and reinstalled. If I will find myself using it like once a month, I'll donate for sure.
