1) To show something to specific usergroup(s) use the following code:
HTML Code:
<if condition="is_member_of($bbuserinfo, x,y,z)">codes</if>
2) They just have changed the first visit message which is always shown to unregistered users. You can edit it from AdminCP.
- AdminCP -> Languages & Phrases -> Search in Phrases

- Check "Phrase Variable Name Only"
- Click Find button.
Good luck.
