How to disable ability to subscribe to forum for certain usergroups

[mrkhm]

Hi,

I would like to disable the ability to subscribe to certain forums via the forum "tools" menu for certain usergroups for a specific forum, so that the ability to subscribe for daily or weekly updates is only available to a certain usergroup for that forum.

I tried to use the "if condition bbuserinfo usergroup... , do not show button to subscribe" but then i realised for savvy people they can work around this by just going directly to http://www.myforum.com/subscription....bscription&f=2

i really wish this was an option in the forum permissions page, amongst the options of can post poll or can view others threads, it would be nice to have "can subscribe to forum"

Any ideas? please
