I see that if one use wordpress.com it creates a file name similar to the subject of your post.
Example:
http://pietpetoors.wordpress.com/2009/01/17/can-you-make-money-from-forex-trading/
But if I create a new subject on the blog on my own domain it just gives it an ID
Example:
http://pietpetoors.com/blog/?p=3
Is there a plugin I can install on my own blog which will enable my blog to also create a unique file name instead of an ID?
