The site was relaunched in 2012. It's been broken ever since. :(

They should really add a list of where you commented, it's very annoying not having that option.

Good question!
I struggle with the same!
Dozens of options are missing.
Where are the fun listst wh named the most songs, i can not delete comments, i can not see to which songs i commented (not clickable).
I can not search in specific category music, etcetera etcetera.
Not much fun anymore....
