Install it in a subfolder of public_html and link to it. When you are ready, you can swap Wordpress and SMF around if you want. It would require downloading the files for both, reuploading to the right places, then change each script's settings. Or the simple way is to use a redirect in .htaccess to go to the Wordpress folder first then link to SMF there. This would be after you are done tweaking.

What kat meant by changing settings

Normal settings whether forums/blogs need to have the exact URL location of the script

Like if you had your forums located at "mydomain.com/forums"  the settings of the script would also show "mydomain.com/forums"  now lets say we moved the forums to a folder named say "test", then we would need to edit the settings to say "mydomain.com/test", make sense?

Redirect to a Different URL using .htaccess
You can use .htaccess to redirect users to a different URL. The .htaccess looks for any request for a specific page and if it finds that request, it forwards it to a new page you have specified.

The syntax is:

redirect accessed-file URL-to-go-to

There are 3 parts;


(i) the Redirect command,
(ii) the location of the file/directory you want redirected, and
(iii) the full URL of the location you want that request sent to.


These parts are separated by a single space and should be on one line.

For example, if you want to redirect users from oldfile.html in the www directory of your account, myaccount, to newpage.html, the syntax should be


redirect /~myaccount/oldfile.html http://www.mydomain.com/~myaccount/newpage.html

Anyone going to http://www.mydomain.com/~myaccount/oldfile.html will end up on http://www.mydomain.com/~myaccount/newpage.html. Please note that the URL has to be full, even if you're going to send the users to another page on your own site.

You can also redirect an entire directory:

redirect /~myaccount/old_dir/ http://www.mydomain.com/~myaccount/new_dir/

Anyone going to http://www.mydomain.com/~myaccount/old_dir/filename.html will end up on http://www.mydomain.com/~myaccount/new_dir/filename.html.

After you have uploaded the altered pages, you should test your redirect by going to the old URL.
