[Wolves] MySQL - equi-join DISTINCT

[Philip Harper]

Ah now found another way to do it without joining tables and complex 
SQL, I wanted to display on my site a list of users who recently logged 
in, but I can do it much easier to by using some very simple SQL to 
return users who logged in during the last month, and limiting it to 30.
