I made a plugin to show an extra profile tab, So yes, it's possible. via plugin, or template mod.
custom user fields is also supported in 1.1 of xenforo.
Can I have stars or any group image under username, different colors for usergroups, show info like registration date, likes received / given and custom user field.
I need custom user field so that members can mention which book they are reading currently etc.
Don't want to create another thread, only one last question. As official IPB converter is out now, so if I mybb > IPB > xF will I be loosing passwords ?
