With phpbb seo there's also the members profiles url that can be rewritten this way :
zeforums.com/nickname-u2.html
instead of zeforums.com//memberlist.php?mode=viewprofile&u=2

Anyway to do this with this extension? It would be a pleasure, as this extension is really lighter than phpbb seo (a lot less files and size), and doesn't write anything in the tables of the database (phpbb seo does), using test page speed in google, it also seems to be a little bit faster than phpbb seo.
Thanks for your answers,
