I’ve never used this software, but Free is one of my favorite words, so I’m going to try it out. It looks like this offer is available until 2 AM Central, 9/11/09.
You have to download and install it before the offer expires, but according to my reading, you will then have a fully-functioning copy of this software. Here are the limitations, from the enclosed README:
1) No free technical support
2) No free upgrades to future versions
3) Strictly non-commercial usage
Read more and download here, then come back and tell me what you think of it!
