Here is a part of the authorization code on the site:
<table border=0 cellspacing=2 cellpadding=2> <tr> <td>Ваше Имя:</td> <td colspan=2><input type=text name=login value='' maxlength=20 style='width:155;'></td> </tr><tr> <td>Пароль:</td> <td><input type=password name=pass value='' maxlength=20 style='width:120;'></td> <td><img border=0 src="i/keyboard2.gif" style='cursor: hand' onClick="KeypadShow();"></td> </tr> <tr> <td colspan=3 align=center><input type=submit value='Войти' class="wbtn" style="width:80;"></td></tr> <tr> <td colspan=3 align=center><input type=button class='wbtn' value='Регистрация' onclick='window.location="reg.php"'></td> </tr></table>
