ICQ profile link leads to a webservice that is no longer active

About a year ago, ICQ operator put down webmessage service (possible due to a massive DoS attack). Since then, phpbb's link to ICQ leads to a webpage with empty search results. It would be nice to have the icq link changed to something more meaningful, like user's profile. Proposed solution:

In viewtopic.php:
FIND
==
$user_cache[$poster_id]['icq'] = 'http://www.icq.com/people/webmsg.php?to=' . $row['user_icq'];
==
REPLACE WITH
==
$user_cache[$poster_id]['icq'] = 'http://www.icq.com/people/' . $row['user_icq'] .'/';
==

In memberlist.php
FIND
==
'U_ICQ' => ($data['user_icq']) ? 'http://www.icq.com/people/webmsg.php?to=' . urlencode($data['user_icq']) : '',
==
REPLACE WITH
==
'U_ICQ' => ($data['user_icq']) ? 'http://www.icq.com/people/' . urlencode($data['user_icq']) .'/' : '',
==
