i'm just saying, look in the file /actions/login.php and at the bottom change this:

system_message(elgg_echo('loginok'));
forward($forward_url);

for this:

system_message(elgg_echo('loginok'));
forward(<yourpage>);

 

There's PlugIns to do that ;-)
[ maybe pre 1.8 but not not much work to ugrade the code ]

I get a server error 

The website encountered an error while retrieving /action/login

tou need to put the url like this:

forward('blog');

forward('dashboard');

forward('http://redvabel.com');

forward('http://community.elgg.org');

jeje sorry for the spam :p

Thanks Angel your da bomb.

In case anyone wants to forward directly to the users profile that logged in, the code is

forward("profile/$username");

The best option is to create an eventhandler for login and then do the forward to the desired URL.
