Assuming you're using the default template, go to /lib/tpl/default/ and find design.css. If not using the default template, go to the appropriate template folder, of course. On line 495, try changing float:right to float:left. You may also need to change the float:right on line 513. I think those two should do it, but can't be sure, of course, since I haven't tested them. Also, look at the source of the wiki page and identify any styles that would have to be changed, then change accordingly on design.css. Muck around for a while and eventually you'll get the effect you want. :-)
