Heh, I just did a search for that guide using a cut&paste from the exact title. Ended up at the bottom of the results page. Methinks the burning board search logic is a simplistic one at best. Anywho, when I want tweaked results, I always resort back to google. Thusly:

google.com
In the search box, type
site:dual-boxing.com Guide to getting Keyclone to work with EQ2

BAM! First link. :P
