To make this short, I will show what I need exactly. Here is the site, it shows some info about game stats once entered username and region.

How can I make remote submitting these forms to parse pages for different users?
THis can be done by copying the same http request that the remote form makes when it submits.
See the following form,
<form action="submit.php" method="post">
<input type=text name="username" />
<input type=text name="password" />
<input type=submit name="submit" value="Submit"/>
</form>
When this form is submitted there is an http request sent to submit.php on the remote host with post method. and in the body these fields reside.
username=MYUSERNAME&password=MYPASSWORD&submit=Submit
The http request looks like
POST submit.php
Host: remotehost.com
Accpet: */*
Content-Type: x-www-form-urlencoded
Content-Length: 43
username=MYUSERNAME&password=MYPASSWORD&submit=Submit
All you have to do is mimic this request.
Curl is a popular library for this task.
