Hide tags

Right now, the coding

Code:

[hide]Some message or link[/hide]

will hide the message until somebody posts.

Is there an option where I can do something like

Code:

[hide="30"]Some message or link[/hide]

where it will require the user to have a certain number of posts before the user can see the hidden block?

Thanks in advance.

No, sorry, that's not possible. You can still give extra permissions for a group to enter a special forum ("Forum / Permissions"). You'd have to simply add now the users with 30+ posts in that group.
