I wanted to find more a more detailed explanation before posting, here goes anyway.\n\n[URL='http://xenforo.com/community/threads/using-forum-pms.12641/#post-166397']Using forum PMs[/URL]\n[QUOTE]They are called Conversations in XenForo. Click on my avatar and you'll see 'Start a Conversation'[/QUOTE]\n\nI believe the reason for the name change is one of which I like. PM's are short for Private Messaging. Conversations not only allow you to have private messages, but also allows you to invite anyone into the conversation. Anyone within the conversation has an option to leave. This works basically the same as a conference room where multiple people can participate in the conversation.
