Removing "members" from BP URLs

Hi: I’ve noticed that there are a few plugins that will shorten BP URLs like mysite.com/members/username to just mysite.com/username , removing “members” from the URL string. Instead of loading one of these plugins, I assume there is a way I can do this by modding either the site .htaccess file and/or possibly the wp-config file. Anyone know the specific code that would accomplish this? My thanks in advance —
