I just wanted to say thank you for making Fritzing.  I made an open source motor controller for electric cars, and had to get a friend to do the layout so the boards could be made cheaply.  Free software usually hamstrings you to go to places that are very expensive.  Everyone keeps trying to send me illegal copies of very expensive software that can generate gerber files, but I've been holding out to save $1500 for Eagle.  I think this will work well for me.  Thank you!  I have a 1000amp 150v controller schematic all ready to be layed out.  Also, I just finished a bms for lithium batteries, as well as a 6kw charger.  I've been stuck getting 2 or 3 boards for like $300 from the free software company for my testing, which has dramatically slowed the process.
