Real name in Orca Forums

Do you know which file(s) needs to be altered with what changes? Many thanks! Blogs are also requiring this change, so if you have any ideas for that too they will be most appreciated!

Open the modules\boonex\forum\integrations\base\callback.php find and replace nickname with first name

Thanks SashaE. I can't seem to get the right combination. This line " 'PosterNickName' => $sUser," seems like the most likely suspect, but I cannot see where to define  $sUser. I need first and last name, so assume it will be something like this "$sNick = $aUser['FirstName'] . ' ' . $aUser['LastName'];" Thanks for your help!
