Hey. On the vanillaforums.org forum, @Username produces a list for selecting what user your trying to reference. How do you replicate this on a self hosted vanilla forum. I can't find an addon for it.
The MentionsLookup plugin could just be what you're looking for: http://vanillaforums.org/addon/mentionslookup-plugin
Add Pages to Vanilla with the Basic Pages app
Thanks @Shadowdare, that's it.
