mod_rewrite regular expressions

RewriteCond %{HTTP_HOST} ^([^\.w{3}]+)\.voosu\.com$ [NC]
RewriteRule ^.*$ http://www.example.com/user.php?id=%1 [P,L]

Here's what I'm trying to do:

anyusername.example.com --> www.example.com/user.php?id=anyusername

Everything works fine, except one thing.

Before I redirect I want it to check for any mention of "www" (so that
there's no continuous loop) and maybe a few other terms in the
subdomain (let's say "private" for the sake of discussion) that I don't
want people to register as usernames. So this means www.example.com and
private.example.com wouldn't get used in this RewriteRule.

The problem is w{3} rejects a subdomain that has even just one "w" in
it. This means no one on my site can have a "w" in their name, which is
bad. What do I do to fix this?

Second, I don't even know how to include "private" or any other term i
want excluded into the regular expression.

Can somebody help me? I've tried googling this and looking up the most
obscure and complicated web sites but I can't find anything easy to
understand.

Thanks!

IIRC a negated class -[^..]- takes all characters literal and thus makes the
quantifier -{...}- useless. Some versions allow
^([^\.(w{3})]+)\.example\.com.

Feel free to test this thought
RewriteCond %{HTTP_HOST} !^(www|private)\.example\.com$ [NC]
RewriteCond %{HTTP_HOST} ^([^\.]+)\.example\.com$ [NC]
RewriteRule ^.*$ http://www.example.com/user.php?id=%1 [P,L]

P ... do you realy want to proxy, consider remapping

What's the difference and how would I do this?
