that hack still uses the normal login way.
so that is member.php
find in member.php under login section:
PHP Code:
eval("standardredirect(\"".gettemplate("redirect_login")."\",\"index.php?s=$session[dbsessionhash]\");");
and change that to a custom made template.
i think that is a solution. but if you have any other login points, those will get the custom template too. so it might conflict.
tell me if you have multiple login points and i'll find a better way.
