Good mod, however :
1) If I set up an "Over 18s" forum, it STILL shows in the forum list to under 18s. This is not good. It makes them curious

2) When setting things in the vBulletin control panel, you should use a drop down menu (defaulting to "older") rather than a text entry field.
I've had to uninstall this mod because my teen users were complaining that there were forums they could not see. I've installed
this mod instead. I do think that Age Lock is a better mod, however, it lacks the ability to hide forums from the forum list. If it had that feature I'd definately use it instead.
