One of the things that is near and dear to me is saving money and finding free solutions to things that cost a lot of money - software is one of them. You may ask why I use dotmac and Sandvox if I find Open Source and freeware solutions palatable, that's simple - they work and I don't have to. There is absolutely no reason to remove something you are comfortable and meets all your requirements whether paid for or not.
Many who publish this type of information are militant in their use of freeware, I am not. Please enjoy the reviews and links to these items, but remember I offer no guarantees to the author's continued support or ability to continue publishing their software.
