Instead we have taken care to import all of your users into our system. Unfortunately there is one downside. Because both WordPress and Textpattern uses a strong encryption hash with passwords, it is impossible to decrypt it and we are forced to assign temporary passwords to all your users. <strong>Every user has the same username, but their passwords are reset to password123.</strong> So <a href="/wp-login.php">Login</a> and change it.</p>');

In most cases, we are successful in this preservation endeavor. However, if we cannot ascertain the name of the writer due to discrepancies between database tables, we assign it to you, the administrative user.</p>');
