Hide content of a BB tag to visitors

[ozmodiar12]

I know there is a module to hide links to guests.

Is it possible to do the same for a custom BB tag ?
I create a new tag "NSFW". In it members post NSFW content/links.

I'd like the content to be hidden for guest and be replace by a generic "click here to register & view this ...".

Is it possible ?

Try to add something like this:

<if condition="$show['member']">
{value}
<else />
Sorry, guest, you're not registered. Click <a href="register.php">here</a> and sign up now!
</if>
