There is a site called Gpotato. It's an MMO portal. There aren't any true "free" MMORPGs there either subscription like the big hitters or pay per content. Some games like Runescape have fairly extensive free sections.
I like MMORPGS to myself, and with todays market im surprised you have a hard tine accessing them. Take for instance ARIA games, its a whole brand of free games at your disposal. If your into a long franchise related game try DDO (dungeons and dragons online, if your into simplistic free games try runescape.
