I changed this last night as I noticed it was blocking the whole index for some reason for guest users... Didn't have the necessary details at hand to fix it, so I just switched it to show only the public forums view. I have now revised it to work as expected.

I've been in the middle of tying up the last loose ends (are they endless at times!) of our remaining local customer website projects, and haven't been able to get to the recent questions here yet; I will be getting back to them shortly.
