forum locked to paid subscribtions?

[wassimeh]

Hmmm; the thing that I need it to completely lock all access to the forum, having a message asking users to register.

Only those who paid would have access to the forum actually; guest people can always register as a user but will need to have paid subscription to have access to the forum.

I also need to be able to allow all user to have access to the forum when the time is needed.

Is there a way or does it need a hack?

thanks
