Forum:Private discussion between three people

One of the other admins at The Morphin Grid asked me this on my talk page, but I don't know the answer: "Is there a method by which admins on the wikis can speak privately? I've been looking for something like that, but I can't find it. I wanted to have a chat with you and the other admin about the wiki.

 * You could use IRC 22:28, December 1, 2011 (UTC)
 * IRC, e-mail, skype, chat (if there aren't any other users around), a different, for instance personal, wiki, instant messanger not yet mentioned, and so on and so on.
