On the front page you can see the last 50 reviews. If I could not visit PA for a couple of days obviously I will have missed some reviews. On days with busy activity i guess it does not take long for 50 reviews to be posted and unless you check frequently, a review will come in and dissapear from the last 50 not long afterwards.
As far as I know there is no way to find those missed posted reviews anymore (unless finding them by pure chance on the album page of course).
It would be nice to have a "Review Search" function, similar to "New Posts" in the forum where you could select to view for example the reviews posted from date x to date y for the period that you missed visiting the site.
Ideally the search should also allow you to filter which subgenres you want to see reviews for.
This brings me to another question out of curiosity. Does anyone have statistics about the posting of reviews? eg
How many reviews are posted per day as average?
Are there patterns? for example, on friday evenings it's usually when most reviews are posted, on mondays it's when less are posted etc.
