i have been looking around to find an easy way to modify the actual links to the register/login without much success (not the look of it not the url-redirect).
i've got a WP3.0.1 multisite with buddypress installed. i also have a registration system outside wordpress (but the login process is *not* changed, i.e. the external system is basically replicating the data in WP in the background)
what i have done was changing the links in the core (i.e. in the wp-login.php i manually changed the links). the problem is that whenever i upgrade the changes are lost. i was looking at custom functions in the theme to achieve this but didn't get very far... does anyone have any suggestions?
