I hear that wordpress is the best free website making software. So i want to learn wordpress and at first i am trying to download this free software but i did not understand from where i download it free?
You might wanna try wordpress.com first if you just want to try out the platform itself, it's the same thing without having to install Wordpress yourself. Learning how to install takes a little time when you're new.
You need to go to wordpress.com and download it , if you thinking of learning then go to wordpress. Create one of your free account . No need of downloading it.
Some people say Wordpress is software, the others say website platform and a lot of people also call CMS (Content Management System) and I like the last one. Here you can download the latest version of wordpress, http://wordpress.org/latest.zip or http://wordpress.org/latest.tar.gz
