Activity Filter to not display certain forum

[BlueEye]

Hi guys,

I'm looking for a way to have the results displayed when looking at the sites latest ACTIVITY results to NOT display results from specific forums (i.e., such as a tech support forum).  I see that you can customize some streams based on forums but how do I do this on the main activity stream?  Even better would be to have the option to disable that forum from all activity streams created.

Thanks -

Chad
