A quick note... this list is a list of software that may need to have a license in order to use commercially. Not all software listed is used by the company this was obtained from and is most certainly not all inclusive, either. Some of these are web sites and some of these are software titles.
It's just a great start on a list of useful software that you may find handy in your travels. Feel free to add to it! Enjoy!
