So is there a way to create a private thread with someone if they haven't posted on the forums previously? There are several people in my guild who are "lurkers" on our threads and never say anything. I'd like to send a few of them a private message, but I can't find anywhere to do so if they haven't posted before. Would be great if you could PM them from the Roster or some other central repository for the accounts we have.
They have to have accounts on the system. If they do then you just click the option when making a post to make a thread private. Then on the selection screen just choose the lowest rank on your site and leave it defaulted to all higher ranks also. Find them in the list and select them. The problem with this is they won't show up if they don't have an account.
So if your intent is to get their attention because all they are doing is lurking and they can read most things without making an account and you want to get them to start using the site. Edit your site or have your web master edit it such that all most all thread tags become non public and thus require and account on the site with a minimum rank level.
