I really do love some of the wordpress and joomla themes that are available for free, and also silverstripe which has probably some of my favourite templates. I have decided to learn about wordpress and silverstripe so that I can expand my knowledge, expertise, and design capabilities with regard to designing websites. It also enables me to offer CMS to people who would like it. While I was having a wee look around I started to consider that some of this open source stuff may have contaminated code. I came across the following, which is rather eye opening. I am glad I found it before I started downloading anything!

I really appreciate it when someone takes the time to research these things on behalf of thousands of other code challenged people like myself. Thank you to Siobhan McKeowen for researching this so thoroughly.
