Reviews and how to control them?

[rains]

Hello all,

I have only been able to find on the CP, under

Maximum Values

New Reviews
Maximum number of new reviews to display
(which I have set to 10)
and

Reviews in Productdetails
Number of displayed reviews in the productdetails page
(which I have set to 4)

And while I can see we have 4 reviews under: Reviews

Only one shows

Can someone, pretty please , tell me how and where they can be controlled. I would like all reviews to show. Do they have an age control or something? As 3 are from 2008 and 1, the visible 1 is from 2009.

thanks peeps
