I think the reason we are asking is that currently I have a conversation on Facebook where half the replies are not transferring to Vbulletin - so on Vbulletin there are some very odd replies to posts that are not visible. ... which looks like I am talking to an invisible friend that nobody else can hear.
in teh pro version, it is essential that Forum people who are not on facebook.. appear on the group discussion thread. and visa versa... people who are not members of the Vbulletin forum appear on the thread discussion. would creating a new " Forum Member " account with facebook, allow this "person" to post on facebook. in the same way as a guest post appears on Vbulletin ?
