Before the updato in achievements page, to see the achievements of another user you needed to go: subeta.net/achieve/USERNAME

But now, what's the link? I just know how to see for categories, like: subeta.net/achievements.php/category/NUMBER/USERNAME

http://subeta.net/achievements.php/index/fever

Edit: Swapped the link UN to mine since I realised it doesn't really work when viewing your own.

oh, thank you ^^
