I think it would be great if we could see every comment someone has posted in the group section.
There was a time when we could at least see how many posts someone has made; the number was written below the avatar. (Now this information is gone, for whatever reason.) However, there had never been a list of comments made by a certain user.
This is a common feature available on most forums. If someone has posted an interesting comment, the chance of him having posted further interesting comments is high. I'd always like to learn something new. :)
