How do you make a private pack on wolfquest on multi player

Private games are currently bugged in 2.5.1; some players are able to create a private game, but sometimes, other players are unable to join their session. There's no known reason for the bug but the team does not have funding resources available to fix it at this time.
Normally, you can create a private pack by selecting "New private game" in multiplayer, giving it a valid name and password (if it's filtered, you cannot open a session of that name) followed by your own community username and password -- note: you must have an activated WolfQuest community account to play multiplayer -- and the pack password.

When you have your game online, you must send the password and game name exactly as you entered them. They are case-sensitive!
You can send these via the WolfQuest forum's private messaging feature to your friends or other participants you'd like to invite.

Hope this helps. :)
