Rewrite rule for specific url address

hello

I use Joomla CMS and one of his user management component generate this kind of url:

http://www.mysite.com/menu-link-to-p...rofile/mikefoo

Instead to get this long url, I would like make it more shorter like simply this:

www.mysite.com/mikefoo

I know is possible to rewrite url using .htaccess but don't know how to do for this specific case. In theory is necessary to remove the /menu-link-to-profile/userprofile/ url...

Any suggestions please?

thank in advance
