Anson,
We have a task to add that as an option, but I think in about 6 months, you're the 2nd to ask for it.. so it's not the highest priority thing for us. However, making this change should be very easy. In the /components/com_jfbconnect/controllers/loginregister.php file, search for "function login()". At the end of that section, there's a big block of if statements with references to redirects. You can comment out the first few lines here, and it should do what you're looking for. However, if you have returning user redirection enabled, you may need some other minor changes (which we can help with if this doesn't work). Mainly, make this section look like:
//if ($jfbcLibrary->initialRegistration)
//{
// $redirectId = $configModel->getSetting('facebook_new_user_redirect', 'index.php');
// $redirect = JRoute::_("index.php?Itemid=" . $redirectId, false);
//}
//else
if ($configModel->getSetting('facebook_login_redirect_enable') && !$jfbcLibrary->initialRegistration)
{
$redirectId = $configModel->getSetting('facebook_login_redirect', 'index.php');
The // are comments, so the first if, which redirects new users, simply won't execute.
Hope that helps, but again, if not, just let us know!
Alex
