for a moment i though i was in the wrong website, i like this one better except for the comment section and the colors, i think the comments should go back to how it was before (But at least this way people would not steal ur name and pretend they are you!)
It seems you can change your name freely and be able to ''pretend'' to be someone else, but each account has a specific ID. Like, you know, mine is 162, yours is 2064. Also, you have a list of the topics you've created and all that on your profile's page. Haven't tested the name changing, but someone said she did and it worked. So yeah, outside of the name changing and such, it's now pretty safe :)
No wonder Seungho fell for him ლ(´ڡ`ლ)
