WordPress MU

I'm glad wpmu can now finally work as a true blog service.
I've just installed it, and anyone can now get a blog very easily.
The subdomain part is also working very nicely.
One question though: how can I get rid of the /wpmu part?
I want it to be: sub.example.com
instead of: sub.example.com/wmpu/
If I install it in domain root directory, will the subs be used directly, without the /wpmu/ part?

Yes.

With out without the "/" ???
Like sub.domain.com
or it should be sub.domain.com/ ????
I hate that "/", and I think I should spend some time studying mod_rewrite

the created blog sites can reach without slash trail at the end. so far, the feed only necessary to end with slash trail at the end "http://name.domain.com/feed/"

mv /public_html/wpmu/wp-inst /public_html
update .htacccess
update config
update wpmu-setting
run upgrade script from admin panel
clear cache folder if necessary

And for blogs under directories ???
How to get ride of the slash ???
itdmager; I have tried your .htaccess, and it didn't work :(

Because its for vhosts installed in the root directory only.

I have modified it to match my directory, but still.
