Sorry for my english first

piece of templates/user_logn_form:
<input tabindex=0 type=text size=10 maxlength=25 name="user_usr" value="{$user_usr}" class=textForm>

piece of bb_fucn_vthread.php:
if (!$user_usr) $user_usr=$l_anonymous;
$mainPostArea=ParseTpl($mainPostArea);

Why value of $user_usr does not appear in the input box in the login form?

It interest me because when users sees blank textbox, they left it as is. After, i see messages only from Anonymous =)

But if $l_anonymous wrote in "login" field, probably users will change whis name to another.

if you try a username that exists - without the correct password (because you mistyped or it is not your account) you will see an error message; if you click back there the template will fill in the account you tried.
of course the very first time a user comes in the template cannot "smell" who is trying to get in :-)

Oops.. I didn't think about this :)
Ok, no questions.
