Change the links to something readable

The default link to a page or post in wordpress looks  something like this http://www.songshu.org/?p=123 , the page is indicated with a number and since we use DNS because humans do not remember 32 bits addresses it make sense for our readers to change this default in to something more readable, also it will make more sense to any search engine if it can use the index the titel of your page using words relating to your content.

You can change the default in the “permalinks” settings to any custom structure you like, as usual you have as many options as opinions on which structure is best. Google away to find out for yourself but i decided to simply go for a custom structure like this /index.php/%postname%

Not sure if this is the best but i kind of like the result, it makes the links to your pages look like this http://www.songshu.org/index.php/change-the-links-to-something-readable
