I used Mepis Linux when I first started with Linux many years ago. I still have an active install of 6.5.02 running on one of my boxes on my home network. It still gets security updates and still works fine.
Version 8 is out now, I always keep a copy of their most recent live cd in my kit, and, it is one of the distros I would recommend to Linux newbies (it's very newbie friendly).
I would also like to say that it has one of the most helpful communities in Linux. Their forums are community driven and worth the read. Link here: http://mepislovers.org/forums/index.php .
