You can configure your default server in the general options near the bottom of the page: http://mabination.com/profile.php?do=editoptions (have to be logged on for it to take effect, otherwise it's in default alphabetical order).
The other tools will also be getting a design update to sort of match what I did to the housing search.
Housing search is also CPU intensive since it has to go grab all the data, and then work with it and print out what you see, every time you do a search or click to go to the next page. So if I notice it being used too much I'll first allow it only to registered users, and then to users with X post count if I have to.
