WordPress MU

I have uploaded the wpmu program to a folder at mysite.ca I want the site to open at mysite.ca instead after it is built. I have a wp site set up in a separate folder and this allows me to redirect to open in home directory instead of the installed folder. I don't want to activate in the home directory until the new version is complete. How do I achieve this measure to have the wpmu open in the mysite.ca after it is complete instead of mysite.ca/folder. I tried on a previous version of WPMU and got an error could not find applicable application.

You might be able to do that with extra rewrite rules for specific IPs that redirected to index-wpmu.php instead of index.php. The specific IPs would be the developers.

Thanks Guru
Would that be a .htaccess and index.php in the mysite.ca/that calls the /folder/index-wpmu.php ?

From what I have read WPMU is suppose to be as easy to work with as WP
I am sure that people will want to have their index to show up on their theirname.mysite.ca/ and not in a separate folder.

"I am sure that people will want to have their index to show up on their theirname.mysite.ca/"

Is there some reason you can't install MU in the root? that's the easiest way to get what you want.

The reason being not installing in the root, this allows to have a sleeper site incase the Wordpress MU site goes down. The root folder calls the site from various other files and folders. In todays technology we can activate applications from other folders. This procedure is done with the regular wordpress program. Install in subdirectory and call from root directory. I always believe in a back up of some sort so I number index php files in the root to activate different programs. If an application fails I can switch applications and not miss a beat. Well maybe a little beat lol. This way you can have the sub directory but what visitors see is just yourname.mysite.ca instead of the sub directory. Good ways to keep files hidden.

Yep, I know. :) I do it on one of my sites.

Doesn't work in MU yet.
