Hello. I've been using the custom user fields option built-in with XenForo for a little while now, and I wanted to create a paragraph box for any other contact links (e.g. link to a profile page on another forum), but I found that I couldn't use BBCode. I'm sure there is an add-on to allow this, but I think that it should be a part of XenForo's core functionality to allow admins to specify whether or not BBCode is allowed. Cheers!
